Write a C program that reads a single integer number from the keyboard via the scanf function, determines if the number is equal to zero or not, and then either prints out: "The number is equal to zero." or "The number is not equal to zero.
Here is the solution for the above question:
#include <stdio.h>
int main(int argc, char *argv[])
{
int num;
printf("Please enter a number: ");
scanf("%d",&num);
if(num == 0)
{
printf("The number is equal to zero.\n");
}
else
{
printf("The number is not equal to zero.\n");
}
return 0;
}
