Please guide me about this program, that will read a C source file and verify that the number of right and left braces in the file are equal. Use getc() function to read the file.

studying about file handling.

This looks like homework. Therefore, I (and other's here) will not write the code for you.

But this task is not difficult. Just try it yourself:

  1. Set a open (left) brace counter, say cnt=0.
  2. read a int, say c, with fgetc(). If c == -1 'end of file' has been reached, hence goto step 6.
  3. if c ==' {' then increment cnt.
  4. if c == '}' then decrement cnt. Check if (cnt < 0) and report failure (unbalanced brace) in such a case.
  5. goto step 1.
  6. if (cnt == 0) report success, otherwise report failure.
