Resetting a program

[turwaa]

I created this program which lets a user select what type of shape they want to create. I was wondering how I could get it to clear after the user has their shape displayed for them (I don't know where to put the "cls" funtion). Secondly, I was wondering when the person is picking how long/wide/high they want their shape, if they select a word instead of number then the program will tell them to re enter a correct value.

For validation, you could use a loop and strintok (s : string)

That will take in a string, and result a boolean if the string entered is also compatible as an integer.
