Is my logic/algorithm correct for Little Elephant and Candies?

c-plus-plus

#1
#include <iostream>

int sum(int array[], int size) {
  int sum = 0;
   for (int i = 0; i < size; i++) {
       sum += array[i];
   }
  return sum;
}


bool candiesLeft(int array[], int size, int candies) {
    for (int i = 0; i < size; ++i) {
        candies -= array[i];
    }
    if (candies > 0) {
        return true;
    } else {
        return false;
    }
}


int main() {

//Read in test cases
int tc = 0;
std::cin >> tc;

//Decrement test cases
while(tc--) {
    //Read in number of elephants
    int n = 0;
    std::cin >> n;
    
    //Read in number of candies
    int c = 0;
    std::cin >> c;
    
    //n elephants
    int a[n];
    for (int i = 0; i < n; ++i) {
        std::cin >> a[i];
    }
    
        
    int candySum = sum(a, n);
    

    if (candySum > c) {
        std::cout << "No" << std::endl;
            break;
    }
    
    
    bool result = candiesLeft(a, n, c);
    
    if (result) {
        std::cout << "Yes" << std::endl;
    } else {
        std::cout << "No" << std::endl;
    }
    
}

return 0;
}

If the sum of the candies the elephants want is greater than the candies we have, the output should already be no, right?

I had a function called candiesLeft that returns a boolean value. If it is true, then we can give all elephants their candies, hence output Yes. If it returns false, then we output No.

Nvm, I got it correct
