1//first lets create a function
2/*void is for starting something, anything after void will be the name of your
3function which will be followed by () */
4void yourFunction() {
5//your code will be here, anything here will be the code in the yourFunction
6  cout << "Functions"

8//now we have to go to our main function, the only function the compiler reads
