write a program that will display one if you enter any number without it will display zero in c?

Answer 1

You can use the following C program to display "1" if a user enters any non-zero number, and "0" if the entered number is zero:

#include <stdio.h>

int main() {
    int num;
    printf("Enter a number: ");
    scanf("%d", &num);
    
    if (num != 0) {
        printf("1\n");
    } else {
        printf("0\n");
    }
    
    return 0;
}

This program reads an integer from the user and checks if it is non-zero or zero, then prints the corresponding output.
