Program was working good until I addded a few codes for the user to check for another piece of data. TNow it's in a continuous loop.
Can a good soul fix my codes:
Thank you...... . . .
-------Configuration: search_key_test - Win32 Debug--------
Linking...
search_key_test.exe - 0 error(s), 0 warning(s)
previous result without the added codes (y/n):
tested: 2/12/02 7:50 p.m Test is ok at first phase
please enter a key to search for: 33
Data found----Press any key to continue
next phase: ask the user to enter another selection
Second phase, the result:
result with added codes asking user to enter another selection:
please enter a key to search for: 17
Data not found
Another selection? (Y or N): y
Data not found
Another selection? (Y or N): n
Data not found
Another selection? (Y or N): Y
Data found----Data not found
Another selection? (Y or N): N
Data found----Data not found
Another selection? (Y or N):
This is a never ending loop, had to forced-cancel the program.
