Question

I’m a complete noob to C and I wondered why if I take a user input why it wont find the file but when I hard code it using:

const char * fn = "/Users/james/Documents/test.rtf";

It seems to work fine?

char text[100];
fputs("File location: ", stdout);
fflush(stdout); 
fgets(text, sizeof text, stdin);

FILE *fp = fopen(text,"r");
if( fp ) {
    printf("\nFile Exists");
    fclose(fp);
} else {
    printf("\nFiles doesn't exist");
}

Any help would be awesome, or just a point to some online source that I have clearly not been able to find.

Answer 1

fgets reads a line and keeps the final newline character. You’ll have to strip that off by

text[strlen(text) - 1] = '\0';

(After doing the proper error checking, of course.)
