I am trying to run below program which i am developing to calculate electricity bill to reduce workload at office as this is a repetitive task so why not use software to do that (i will use this code to do whole calculation process automatically using a database and then write in a text file which will be exported in excel) i am looking to complete this program before end of this month.
It runs perfectly without any error but only for 1 time, when the loop start again then it don't take any input ( but do show all cout statements) and go straight to end of loop where i can press 0 to re run the loop
also, if i use
cout<<"Enter Name: ";
cin.get(name,100);
this code ( to enter name ) after getting rank input then this program skips the input of name and do to next step. It do same thing if i use cin.getline instead of cin.get.
I am using visual studio 2008 to compile this c++ code as win32 application. ( name contains space to thus i need to use method other than cin to get full name and if i use cin.get for every string input then i get runtime error of "stack got corrupted around name")
Any one any idea what is wrong happening with this code?
