statement that causes a function to end in c++

In C++, you can use the "return" statement to cause a function to end. The return statement is used to return a value from a function back to the caller.

Here is an example of how to use the return statement in C++:

int sum(int a, int b) {
    int result = a + b;
    return result;
}

In the above example, the function "sum" takes two integers as input parameters and calculates their sum. The "return" statement is used to return the result of the addition back to the caller of the function.

When the "return" statement is encountered, the function execution is immediately terminated, and the control is returned to the caller. The value specified after the "return" keyword is returned as the result of the function.

It's important to note that if a function has a return type other than "void" (which means the function does not return any value), you must provide a return statement in every possible execution path of the function. If a function does not have a return statement, or if the return statement is unreachable (i.e., it is never executed), it may result in a compilation error or undefined behavior.
