Return statement - Control Structures
How is return statement used in C++?
Explanation
Return Statement stops the execution of the code and returns the flow of the program to the calling function. The "return" function may or may not return a value. Usually all non-void functions must return a value. This belongs to control structures.
return expression;
Result :
The Highest number is::20
In the above example, the return statement control structure is explained in the following manner. the "main()" is a void function so it does not return a value, but the "max" function returns an integer value since its return type is "int".
Syntax:
return expression;
Example :
| #include <iostream.h> void main() { int x,y,h; x=10; y=20; h=max(x,y); cout << "The Highest number is::" << h << endl; } int max(int l, int m) { if (l > m) { return l; } else { return m; } } |
Result :
The Highest number is::20
In the above example, the return statement control structure is explained in the following manner. the "main()" is a void function so it does not return a value, but the "max" function returns an integer value since its return type is "int".
