Return from void functions in C++
The void functions are called void because they do not return anything. “A void function cannot return anything” this statement is not always true. From a void function, we cannot return any values, but we can return something other than values. Some of them are like below.
A void function can return
A void function cannot return any values. But we can use the return statement. It indicates that the function is terminated. It increases the readability of code.
Example Code
#include <iostream>
using namespace std;
void my_func() {
cout << "From my_function" << endl;
return;
}
int main() {
my_func();
return 0;
}Output
From my_function
A void function can return another void function
In this approach, one void function can call another void function while it is terminating. The code will look like this.
Example Code
#include <iostream>
using namespace std;
void another_func() {
cout << "From another_function" << endl;
return;
}
void my_func() {
cout << "From my_function" << endl;
return another_func();
}
int main() {
my_func();
return 0;
}Output
From my_function From another_function
