Is this a problem with strcmp?

Hello again so soon,

Still writing for a file based database, but now I'm trying to search for key strings to retrieve specific lines of data.

My problem is that even though I can see that my two strings for comparison are identical when I print them, the strcmp function refuses to acknowledge them as such.

Have I used it wrong? Or perhaps made another error in my code?

Code:

char ViewInfo()
{
    FILE *fptr;


    fptr=fopen("E://StudentFile.txt", "r");


    char StudentSearch[9], FileString[9], Line[130], Name[20], n[10];


    if (fptr == NULL)
        printf("Unable to open file");


    else
    {
        printf("File opened\n");
        char StudentSearch[10], FileString[10], Line[130];


        fputs("Please enter the student number of the student whose information you would like to view: ", stdout);


        char c=getchar();
        while (c != '\n')
            c=getchar();
        fflush(stdout);


        if (fgets(StudentSearch, 9, stdin) != NULL && strlen(StudentSearch)==8)
        {


            printf("Valid input is %s", StudentSearch);




            do
            {
                fscanf (fptr, "%s", FileString);
                printf("The file says %s\n", FileString);


                scanf("%s", n);


            }
            while(strcmp(StudentSearch, FileString) != 0);


            printf("Yup");
            fgets(Line, 130, fptr);
            printf("%s\n", Line);


        }
        else
            printf("Invalid Input. Student number must be 7 digits long");




    }
    fclose(fptr);

Any tips appreciated, thanks!

line 46 " scanf("%s", n); " was just to prevent the program crashing in an endless loop and so I could see the progress of the file pointer.

Quick guess one has an linefeed on the end (fgets) and the other does not.

What might be a way to fix that? I read somewhere about a Replace function that worked like this:

StudentSearch.Replace("\n\r","");

but this makes absolutely no sense to me and it didn't work anyway.

Also StudentSearch=StudentSearch.Trim(' ', '\n', '\r'); didn't work.

How about the one shown in your previous thread?

Are you referring to this?

Code:

char *newline = strchr(FileString, ' ');
                if ( newline != NULL )
                {
                    *newline = '\0';
                    printf("\nNewline Removed");
                }

If so, what character should I be looking for? I'm still not familiar enough with c to really understand when to use what, so I've already tried ' ', '\n', '\r', and '\n\r' to no avail.

Thanks for the help!
The issue was indeed the linefeed in the gets() value, which was removed using the above method.
