Your chars are uninitialized, so it's good to initialized them to nothing by doing this

 
char myChar[200] = {'\0'};


A few of your getline seems to skip. Try inserting a cin.ignore() above or below it to see if it fixes anything.


Also, can you be a bit more specific? What errors do you need help with in your program?
