What is a value returning function in C++?
A function that returns a value is called a value-returning function. A function is value-returning if the return type is anything other than void . A value-returning function must return a value of that type (using a return statement), otherwise undefined behavior will result. Related content.How do you write a value returning function?
To return a value from a function, you must include a return statement, followed by the value to be returned, before the function's end statement. If you do not include a return statement or if you do not specify a value after the keyword return, the value returned by the function is unpredictable.How to use return value in main () in C++?
The return value of main() function shows how the program exited. The normal exit of program is represented by zero return value. If the code has errors, fault etc., it will be terminated by non-zero value. In C++ language, the main() function can be left without return value.- The return type, which specifies the type of the value that the function returns, or void if no value is returned. In C++11, auto is a valid return type that instructs the compiler to infer the type from the return statement. In C++14, decltype(auto) is also allowed.
