Count Matches

A counting loop increments a result when an element satisfies a condition.

int main(void) {
    int threshold = ;
    int values[5] = {2, 5, 7, 9, 4};

predicate The condition decides whether one element contributes to the count.

counter The counter changes only when the condition is true.
