Question

Write a C function named: div() with one local variable: m to prompt the user to enter one integer for the local variable m. When you call the function, it should display one of the following lines:
If m is divisible by 9 the function displays the message m is divisible by 9
If m is divisible by 3 and not divisible 9 (e.g. 24) the function displays the message m is divisible by 3
If m is neither divisible by 3 nor by 9 the function displays the message m is not divisible by 3 or 9.
Note that in the above three lines, by m, I mean the value of m.

Answer 1

#include <stdio.h>
#include<string.h>

void div()
{
int m;
printf("Enter one integer: ");
scanf("%d",&m);
if(m%9==0)
{
printf("%d is divisible by 9.",m);
}
else if(m%3==0 && m%9!=0)
{
printf("%d is divisible by 3.",m);
}
else if(m%3!=0 && m%9!=0)
{
printf("%d is divisible by 3 or 9.",m);
}

}
int main()
{
div();
return 0;
}
