Question

Write code in C to demo how to test the content of a variable and do some action accordingly.
Add a one line comment above the code to explain the code.

Here is an example code:
/* the following code checks if variable x is divisible by variable y and displays a message accordingly */
int x,y;
printf( "Enter two numbers \n" );
scanf("%d %d",&x,&y);
if (x % y ==0) { // use == to test for equality % returns remainder of dividing x by y could remove ==0(How)?
printf(" Divisible "); }
else
  printf("Not Divisible "); }

Then, write the code using switch statements.

Answer 1

OUTPUT

Enter a digit: 4
That's four

CODE

#include <stdio.h>

int main(void) {

int n;

printf("Enter a digit: ");

scanf("%d", &n);

switch(n)

{

case 1:

printf("That's one");

break;

case 2:

printf("That's two");

break;

case 3:

printf("That's three");

break;

case 4:

printf("That's four");

break;

default:

printf("You entered more than four");

}

return 0;

}
