see function in a C++ program code example

Example 1: How to make a function in C++

//first lets create a function
/*void is for starting something, anything after void will be the name of your
function which will be followed by () */
void yourFunction() {
//your code will be here, anything here will be the code in the yourFunction
  cout << "Functions"
}
//now we have to go to our main function, the only function the compiler reads
int main() {
  myFunction(); //you call the function, the code we put in it earlier will be executed
  return 0;
}

Example 2: how to make a function in cpp

// function returning the max between two numbers
 
int max(int num1, int num2) {
   // local variable declaration
   int result;
 
   if (num1 > num2)
      result = num1;
   else
      result = num2;
 
   return result; 
}
