C Program to count keywords from a keyword text file in a fake resume and display the result-CodePudding

#EDIT: I think the problem is that I put my 2 text files on desktop. Then, I move them to the same place as the source file and it works. But the program cannot run this time, the line:

cok = 0;

shows "exception thrown". // end EDIT

I have the assignment at school to write a C program to create 2 text files. 1 file stores 25 keywords, and 1 file stores the fake resume. The problem is, my program cannot read my keywords.txt file. Anyone can help me? Thank you so much.

    int coK, coR, r, r1;
    coK = coR = r = r1 = 0;
    //Checks if file is unable to open then display error message

            //Copies the wordK to the keywords r index position and increase the counter r by one
            strcpy(keywords[r  ], wordK);

                }//End of else
            }//End of inner while loop
            //Increase the counter by one
            r1  ;
            //Close the file for resume
            fclose(fpR);
        }//End of else
    }//End of outer while loop
    //Close the file for keyword
    fclose(fpK);
    //Display the result
    printf("\n Result \n");
    for (r = 0; r < r1; r  )
        printf("\n Keyword: %s %d time available", keywords[r], keywordsCount[r]);
}//End of main

I think the problem is the text files, aren't they?

The name of my 1st test file is "keywords.txt", and its content is: Java, CSS, HTML, XHTML, MySQL, College, University, Design, Development, Security, Skills, Tools, C, Programming, Linux, Scripting, Network, Windows, NT
The name of my 2nd test file is "resume.txt", and its content is:

I don't see any problem with these 2 files. But my program still cannot open the file and the output keeps showing "Could not open files".

    while ((cK = fgetc(fpK)) != EOF)

If you check the documentation, you can see that fgets returns an int. But since cK is a char, you force a conversion to char, which can change its value. You then compare the possibly changed value to EOF, which is not correct. You need to compare the value that fgets returns to EOF since fgetc returns an EOF on end of file.

if you are in Linux you might not have right privileges to access the files or any file at all.
