It depends on the context.
- it means "no" in functions that check something (like "isatty", "isascii", "isdigit")
- it means "success" in functions whose return value is an error code (0 means no error)
- it means "fail" or "not found" in functions that return a pointer (like strchr or fopen).

Which Keyword is used to return some value from a function?

When is a function executed and where should a function prototype and function definition appear in a source program?
If you want to use prototype it has to be declared before main(). If you have a function of type double with one argument of type int (with name arg), and the function name is func, then we have:#include ...double func(int arg);...int main(...){...return 0;}...double func(int arg){...}
How is main function declared?
int main (void) or int main(int a, char **p)
What is the default return type of a function?
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. By default, it will return zero. To learn more about data science please visit- Learnbay.co

What is a prototype within a program?
Prototyping is done (at least in C/C++) to declare a function and tell the compiler how to use it before the int main(void) part of the program is run. The function is declared after main and is usually done as a style thing. example int function(int); int main(void) { int anumber = 1; x = function(anumber); return 0; } int function(int number) { //do something return number; } et cetera et cetera...
