Transform number by applying rule: even→square, odd→cube Program Code

#include <stdio.h>
int main() {
    int num, result = 0, place = 1, temp;
    printf("Enter a number: ");
    scanf("%d", &num);

        int digit = temp % 10;
        int transformed;
        
        if(digit % 2 == 0) {
            transformed = digit * digit;     // even → square
        } else {
            transformed = digit * digit * digit;  // odd → cube
        }
        
        // Handle multi-digit transformed values
