return use in c++ code example

Example 1: return use in c++

Terminates the execution of a function and returns control to the calling function (or to the operating system if you transfer control from the main function). Execution resumes in the calling function at the point immediately following the call

Example 2: return function in cpp

void printChars(char c, int count) {
    for (int i=0; i<count; i++) {
       cout << c;
    }//end for
   
    return;  // Optional because it's a void function
}//end printChars

Example 3: 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 4: 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
