Question 1

a) The purpose of the program is to print Welcoming text on screen when the program is run.“Variables”—do not have any variables in this program“Input”—do not required any input for this program“Output”—display a welcome text on screen by preprocessor directives printf (“_____”) “ ; ” — Punctuation “\n” — new line

b) /* The purpose of the program is to print text on screen when run.*/

#define MESSAGE “Welcome to this computer programming class!\n”

main( )

{

printf(MESSAGE);

}

c) main( ){

float gross, tax, net; \\ Declarations of Variables

\\ Statementsprintf(“Gross salary: “); scanf(“%f”, &gross); \\ Inputtax = 0.14*gross;net = gross – tax;printf(“Taxes withheld: %.2f\n”, tax); \\Output


Output

Pre-define

New li

Display “By bus”

Display “Own Transport”

If “c” then Display “By walking”



Question 2

i) Flow chart


Start

Set ‘a’= Bus‘b’= own transport‘c’= by walking

If ‘a’

ii) Pseudo code

1. Start

2. Display “ How do you go lecture from your house?”

‘a’= Bus‘b’= own transport‘c’= by walking

3. Input ‘a’ or ‘b’ or ‘c’4. Print output5. Ends

If ‘b’

End

Start

Enter a value for the principal (p)

Enter value for the interest rate (r)

Enter value for the num. of years (n)

Calculate i=r/100f= p*pow((1+i),n)

Display final value f=_____

End
