Here is the simple program in c to find the greatest among three number :#include <stdio.h>

int main() {
    int num1, num2, num3;

printf("Enter the first number: ");
    scanf("%d", &num1);

printf("Enter the second number: ");
    scanf("%d", &num2);

printf("Enter the third number: ");
    scanf("%d", &num3);

if (num1 >= num2 && num1 >= num3) {
        printf("The greatest number is: %d
", num1);
    } else if (num2 >= num1 && num2 >= num3) {
        printf("The greatest number is: %d
", num2);
    } else {
        printf("The greatest number is: %d
", num3);
    }

return 0;
}

You make it short using loop, get user input in array like this#include int main() { int num[3]; for (int i = 0; i < 3; i++) { printf("Enter number %d: ", i + 1); scanf("%d", &num[i]); } if (num[0] >= num[1] && num[0] >= num[2]) { printf("The greatest number is First number: %d ", num[0]); } else if (num[1] >= num[0] && num[1] >= num[2]) { printf("The greatest number is Second number: %d ", num[1]); } else { printf("The greatest number is third number: %d ", num[2]); } return 0; } also you can use ternary operator int max = (num[0] > num[1]) ? ((num[0] > num[2]) ? num[0] : num[2]) : ((num[1] > num[2]) ? num[1] : num[2]); // now print max printf("The greatest number is: %d ", max);
