In this shot, we want to briefly illustrate how the return keyword is used in a function in C++.
return keyword?The return keyword in C++ returns a value to a function. The return keyword is declared inside a function to return a value from the given function.
#include <iostream>using namespace std;// creating a functionint myfunction(int x) {// declaring the return keyword for the functionreturn 10 + x;}int main() {cout << myfunction(5);return 0;}
myfunction(), and pass an integer parameter value x to the function.return keyword for the function. This tells C++ that the expression right after the keyword should be returned whenever the function is called.myfunction and pass an argument, 5, to the function. The output is printed to the console.The return keyword can also be used with two parameters.
#include <iostream>using namespace std;// ccreating a function having two parametersint myFunction(int x, int y) {// declaring the return keywordreturn x + y;}int main() {cout << myFunction(10, 5);return 0;}
myfunction function with two parameter values, x and y.return keyword.myfunction and pass arguments to the function. The output is printed to the console.
