return statement in C++

In C++ programming language, you can't use the return statement to return a value in the function that is declared with void type. In contrast, function declared with a type rather than void must return a value of that type.

//function definitions
void printHello(){
cout<<"Hello World!"<<endl; //correct

int sum(int a, int b){
int s=a+b;
//No a value is returned, then you get an error.

int main(){

//calling the functions
int total=sum(10,20);
return 0;
