Check whether all digits are same Program Code

#include <stdio.h>
int main() {
    int num, allSame = 1, temp;
    printf("Enter a number: ");
    scanf("%d", &num);
    
    int lastDigit = num % 10;
    
    for(temp = num; temp != 0; temp /= 10) {
        if(temp % 10 != lastDigit) {
            allSame = 0;
            break;
        }
    }
    
    if(allSame) {
        printf("All digits are same\n");
    } else {
        printf("Digits are NOT all same\n");
