Debugging errors in c++
- by user1513323
I was working on a program that printed out the word count, character count and line count depending on the user's input. But I keep getting these error that are completely unknown to me. I was wondering if anyone could help.
** I've changed it from previous mistakes and am still receiving errors. Sorry I'm new to C++.
The errors I got were
filestat.cpp:47: error: ‘line’ was not declared in this scope
filestat.cpp: In function ‘int wc(std::string)’:
filestat.cpp:55: error: ‘line’ was not declared in this scope
filestat.cpp: In function ‘int cc(std::string)’:
filestat.cpp:67: error: ‘line’ was not declared in this scope
