how return works in c++ code example

Example 1: return function in cpp

// Multiple return statements often increase complexity.
int max(int a, int b) {
    if (a > b) {
        return a;
    } else {
        return b;
    }
}//end max

Example 2: return function in cpp

// Single return at end often improves readability.
int max(int a, int b) {
    int maxval;
    if (a > b) {
        maxval = a;
    } else {
        maxval = b;
    }
    return maxval;
}//end max
