Chap10[D]g Use structure to check dates

Write a program that compares two given dates. To store date use

structure say date that contains three members namely date,

month and year. If the dates are equal then display message as

"Equal" otherwise "Unequal".

void main()

{

int i,f=0;

struct date

{

int date;

int month;

int year;

};

struct date d[2];

for(i=0;i<2;i++)

{

printf("\nEnter day for the %d) date\n",i+1);

scanf("%d",&d[i].date);

printf("\nEnter the month for the %d) date\n",i+1);

scanf("%d",&d[i].month);

printf("\nEnter the year for the %d) date\n",i+1);

scanf("%d",&d[i].year);

}

if(d[0].date==d[1].date)

{

if(d[0].month==d[1].month)

{

if(d[0].year==d[1].year)

{

f=1;

}

}

}

if(f==1)

printf("\nThe dates are equal");

else

printf("\nThe dates are not equal");

}

Chap10[D]e Displaying data in structure with condition

There is a structure called employee that holds information like

employee code, name, date of joining. Write a program to create

an array of the structure and enter some data into it. Then ask the

user to enter current date. Display the names of those employees

whose tenure is 3 or more than 3 years according to the given

current date.

This program doesn't check whether your date is correct so even if you

put 99990001 it is still valid.

void main()

{

int i,k;

char date[8];

char j[1];

struct em

{

int code;

char name[20];

char datej[8];

};

struct em e[5];

for(i=0;i<5;i++)

{

printf("\nKey in code, name and date(ddmmyyy) of employment for %d)

employee\n",i+1);

scanf("%d%s%s",&e[i].code,e[i].name,e[i].datej);

if(strlen(e[i].datej)!=8)

{

printf("\nYou keyed the date wrongly, key again");

i--;

continue;

}

}

while(1)

{

clrscr();

printf("\nEnter current date\n");

scanf("%s",date);

for(i=0;i<5;i++)

{

k=0;

k=funccheck(date,e[i].datej);

if(k==1)

printf("\nEmployee code= %d Employee name= %s has tenure more

than or equal 3 years",e[i].code,e[i].name);

}

printf("\nKey q to quit or any other key to continue\n");

scanf("%s",j);

if(j[0]==113)

break;

}

}

funccheck(char *date,char *datej)

{

int a,a1,i,t;

for(i=7,t=1,a=0;i>3;i--,t*=10)

{

Chap9[F]e Creating a dynamic calendar

Develop a program that receives the month and year from the

keyboard as integers and prints the calendar in the following

format.

Note that according to the Gregorian calendar 01/01/1900 was

Monday. With this as the base the calendar should be generated.

Modify the above program suitably so that once the calendar for a

particular month and year has been displayed on the screen, then

using arrow keys the user must be able to change the calendar in

the following manner: Up arrow key : Next year, same month

Down arrow key : Previous year, same month Right arrow key :

Same year, next month Left arrow key : Same year, previous

month If the escape key is hit then the procedure should stop.

Hint: Use the getkey( ) function discussed in Chapter 8, problem

number [L](c).

}

else if (words[i][j]==words[i+1][j])

continue;

else

break;

}

}

for(i=0;i<10;i++)

{

printf("\n%s",&words[i][0]);

}

}

Note: This code only works for small letters.

If you want to use uppercase letters then create a function to convert all

uppercase to lowercase first then do the main code then at the end

convert back to uppercase and print.

Chap9[F]a Replacing words in sentences

Write a program that uses an array of pointers to strings str[ ].

Receive two strings str1 and str2 and check if str1 is embedded in

any of the strings in str[ ]. If str1 is found, then replace it with

str2.

char *str[ ] = { "We will teach you how to...",

"Move a mountain",

"Level a building",

"Erase the past",

"Make a million",

"...all through C!"

} ;

For example if str1 contains "mountain" and str2 contains "car",

then the second string in str should get changed to "Move a car".

Note: There is a limitation to this code

*** Except for the first sentence if the word you want to replace is longer

than the original word the program doesn't work ideally.

So the replace function seem in the program works only on single line

sentences(i.e One dimension char array).

The reason for this is that a longer word pushes the location of the last

letter of the sentence into the next sentence.For example if a is replace

with two in the mountain sentence then the last letter "n" of mountain

gets pushed to a location at around "e" in "Level" in the next sentence.

The code in replace only accounts for longer words in one sentence.

If you want to overcome this limitation then add a new string array.

"replace" function becomes replace(char *m,int j,char *n,char *new)

where char *new is a blank array defined in main(). Then pass this blank

array to char *new in replace function.

Chap 9[D]d Working with strings is fun

Write a program that extracts part of the given string from the

specified position. For example, if the sting is "Working with

strings is fun", then if from position 4, 4 characters are to be

extracted then the program should return string as "king".

Moreover, if the position from where the string is to be extracted

is given and the number of characters to be extracted is 0 then

the program should extract entire string from the specified

position.

void main()

Chap8[L]d Creating grid puzzle

Very often in fairs we come across a puzzle that contains 15

numbered square pieces mounted on a frame. These pieces can be

moved horizontally or vertically. A possible arrangement of these

pieces is shown below:

As you can see there is a blank at bottom right corner. Implement

the following procedure through a program:

Draw the boxes as shown above. Display the numbers in the

above order. Allow the user to hit any of the arrow keys (up,

down, left, or right). If user hits say, right arrow key then the

piece with a number 5 should move to the right and blank should

replace the original position of 5. Similarly, if down arrow key is

hit, then 13 should move down and blank should replace the

original position of 13. If left arrow key or up arrow key is hit then

no action should be taken. The user would continue hitting the

arrow keys till the numbers aren‟t arranged in ascending order.

Keep track of the number of moves in which the user manages to

arrange the numbers in ascending order. The user who manages it

in minimum number of moves is the one who wins. How do we

tackle the arrow keys? We cannot receive them using scanf( )

function. Arrow keys are special keys which are identified by their

„scan codes‟. Use the following function in your program. It would

return the scan code of the arrow key being hit. Don‟t worry about

how this function is written. We are going to deal with it later. The

scan codes for the arrow keys are:

up arrow key – 72 down arrow key – 80 left arrow key – 75 right

arrow key – 77

/* Returns scan code of the key that has been hit */

Fibonacci Sequence

Write a recursive function to obtain the first 25 numbers of a

Fibonacci sequence. In a Fibonacci sequence the sum of two

successive terms gives the third term. Following are the first few

terms of the Fibonacci sequence: 1 1 2 3 5 8 13 21 34 55 89...

void main()

{ void Fib(float,float,float);

float e,d;

/* i put d=24 because the function will start off by printing 1 and starts

counting its recursion only after the first digit so if i want 25 numbers its

25-1=24*/

d=24;

e=1;

printf("\Display Fibonacci sequence");

Fib(d,e,1.0);

}

void Fib(float x,float a,float b)

{

if(a==1)

printf("\n1");

if(x==0)

exit();

printf("\n%f",a);

if(x==1)

exit();

b=a+b;

printf("\n%f",b);

Fib(x-2,a+b,b);

}

Finding prime numbers

A positive integer is entered through the keyboard. Write a

function to obtain the prime factors of this number. For example,

prime factors of 24 are 2, 2, 2 and 3, whereas prime factors of 35

are 5 and 7.

Using recursion:

void main()

{

int x;

printf("\nInput an integer\n");

scanf("%d",&x);

prime(x);

}

prime(int x)

{

int a;

for(a=2;a<=x;a++)

{

if(x%a==0)

{

printf("%d ",a);

prime(x/a);

break;

}

}

}

without recursion

void main()

{

int x;

printf("\nInput an integer\n");

scanf("%d",&x);

prime(x);

}

prime(int x)

{

int a;

for(a=2;a<=x;a++)

{

if(x%a==0)

{

printf("%d ",a);

x/=a;

a--;

}

}

}

power of the second value");

scanf("%f%f",&x,&y);

z=power(x,y);

printf("\nThe answer is %f",z);

}

float power(float a,float b)

{

float c;

if(b==0)

return(1);

if(b==1)

return(a);

else

c=a*power(a,b-1);

return(c);
