1. WAP to calculate the ranges of char, int, long int, unsigned char,unsigned int, and unsigned long int.

Answer:-

#include

#include

int main()

{

printf(" Range of char -> %d to %d\n", CHAR_MIN, CHAR_MAX);

printf(" Range of int -> %i to %i\n", INT_MIN, INT_MAX);

printf(" Range of long int -> %ld to %ld\n", LONG_MIN,LONG_MAX);

printf(" Range of unsigned char -> 0 to %u\n", UCHAR_MAX);

printf(" Range of unsigned int -> 0 to %u\n", UINT_MAX);

printf(" Range of unsigned long int -> 0 to %lu\n", ULONG_MAX);

return 0;

}

Output:-

Range of char -> -128 to 127

Range of int -> -2147483648 to 2147483647Range of long int -> -2147483648 to 2147483647

Range of unsigned char ->0 to 255

Range of unsigned int -> 0 to 4294967295Range of unsigned long int -> 0 to 4294967295

2. WAP to display the bit pattern of any integer. Your program shouldhandle the case of negative numbers efficiently.

Answer:-

#include#include


3/25

main()

{

int j,a[8],n,g=0,i=0,k,m;

printf("Enter a number :");

scanf("%d", &n);

if(n>0)

{

printf("Bit Pattern of %d is ", n);

while(n!=0)

{

if(n%2==0)

a[i]=0;

elsea[i]=1;

n=n/2;

i++;

}

for(j=i-1; j>=0; j--)

printf("%d", a[j]);}

else

{

n=n*-1;

while(n!=0)

{

if(n%2==0)

a[i]=0;else

a[i]=1;

n=n/2;

i++;

}

for(j=i-1;j>=0;j--)

{

if(a[j]==0){


4/25

a[j]=1;

}

else

a[j]=0;

}

Its binary form is 101

3. A palindrome is a word , phrase or sentence that reads the sameway either forward or backward.(example-noon, madam ).If we

disregard punctuation and blank spaces then the sentence Rise to

printf("Enter x2 :");

scanf("%d",&(x.x2));printf("Enter y2 :");

scanf("%d",&(x.y2));

dis=sqrt(pow(x.x2-x.x1,2)+pow(x.y2-x.y1,2));

printf("Distance between (%d ,%d) and (%d ,%d) is

%f",x.x1,x.y1,x.x2,x.y2,dis);

Enter x1: 2

Enter y1:3

Enter x2:3Entery2:1

{

d = rand();

while(d>1)d/=10;

sum += d;}

printf ("Mean of 100 random numbers: %lf\n", sum/100);

return 0;

}

Output:-
