when you make a function, it has a return type. for example int myFunction(){ int a=5; return a; } The above code will return the variable 'a' that is 5 (an integer) when the function is finished running successfully. however this function will only return integers. It cannot return any other type of variable (string, bool, double, float, etc.) So what is a void? a void is a function that does not return anything, for example void printHello(){ cout<<"Hello!"<<endl; } the function will print out "Hello!" but will not return anything. in other words, no "return [something] at the end. hope this makes it clear.
