I was wondering if there was a way to have a string array to store both numbers and letters. For example, Im writing a digital signal generator program, the user is to input values 0-9,#,*,A-D. My teacher has never went over strings until today, in which he gave a 5 minute overview of it. So Im completely confused.
I need to store these values in an array so i can use a switch statement to pick different frequencies. For example if the 0th value in the array is A the frequency would be 697 HZ. The only problem is that I don't know how to use strings to read a value in the array everytime I try it freezes on me.
