[Solved] Consider this function that returns the sum of positive numbers until a zero is found:int sumUntilZero(int arr[], int size) { int sum =... }What will be the output for input array {1, 2, -1, 0, 5}? | C

C - Loop Control Statements

Consider this function that returns the sum of positive numbers until a zero is found:

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

What will be the output for input array {1, 2, -1, 0, 5}?

Step-by-Step Solution

Solution:

Step 1: Trace the loop and sum
Elements: 1 (sum=1), 2 (sum=3), -1 (ignored), 0 (return sum=3).
Step 2: Return sum when zero found
Function returns 3 immediately when zero is found at index 3.
Final Answer:
3 -> Option C
Quick Check:
Return inside loop returns sum at zero [OK]

Quick Trick: Return sum immediately when zero found inside loop [OK]
