"Run-Time Check Failure #3" -- variables cannot be initialized
I am trying to write this program that finds the area and the perimeter of a specific figure. Everything seems to be working other than the fact that it keeps telling me, "Run-Time Check Failure #3 - The variable 'A_Trig' is being used without being initialized." This goes for all the variables that either start with A_" "or P_" " in lines 18 and 19(I made the text bold where it is telling me where the error is). Can someone please help me solve this problem? I have been attempting for the past few hours and still cannot get it. Thanks a lot!

It means that you are using A_Trig etc without having first given them a value. Perhaps you need to move the assignments to Area and Perimeter down below where you calculate the values for the A_ and P_ variables?
do you mind showing me what you mean? I am really new at this so it would be a lot easier if I could visually see what you mean. Thanks.
