File and String Program Not Running, in plain C lang

[airfire29]

Hi my code is not running so I ask that someone test this for me and also review if my logic and syntax is correct.

The assignment is to write a program that statistically computes similarity of C syntax with another program; a same and a different. The one used here is in C language, it's called Battleship.cpp. The program must open a file and read line by line for keywords and then produce statistics.

The reason my code is not running is the fopen function is failing and it goes to return -1. I am using MS Visual Studio 2013 and there are no compiler errors after turning off deprecation. I do see, however, this error UMEngx86.dll'. Cannot find or open the PDB file. The file being opened is in my source folder.

  #include <stdlib.h>
#include <stdio.h>
#include <string.h>

	const char lines, blank = " ", comment1 = "//", comment2 = "/*", ints = "int", longs = "long", floats = "float", doubles = "double", chars = "char", ifs = "if", elses = "else", fors = "for", switches = "swtich", semicolons = ";", structs = "struct", arrays = "[", blocks = "{";

First
On line 14: The name of the file is "Battle_ship.txt". Are you sure that you want the unusual name "Battle_ship.cpp"?

Second
Since you use a relative path: Is the file actually where the program expect it? For debugging you might use an absolute path like "C:\\test\\Battle_ship.cpp" or so.

Third
Lines 21 to 24: You're reading all lines from the file into one buffer. That means: After reading from the file you process only the very last line.
