I am creating a calculator and have 4 textboxes. I need to know what functions I need to delete the number '0' from a string of numbers such as, "0852" so it can look like "852." My goal is for the program to check the user input after the user has pressed the 'enter' button to go to the next textbox. I know there are functions that can check each character in a string and search for a specific character. So I just need to know the functions. I'm sure I can implement it in my program correctly. thanx in advance!!! P.S. This is for C++ MFC VS2005.
