Passing of values from text file to array

Question

I\'m having some problems with my code.

My program calculates the amount of resistance based on the color of the three bands coming from an input file, then printing

Answer 1

The first mistake in the code I see is that you are not removing the spaces from the input string, which you can do by changing the token separator string to " ,". You could also simplify the code a bit by removing the newline at the same time.

It is also prudent to limit the range of i since any line with more than 3 colours will break the array colord[], and this would have drawn your attention to the second mistake, which is you forgot to reset i within the loop, and this could explain why you are getting crashes.

while(fgets(color, size, fptrin) != NULL) {
    i = 0;                                  // reset `i`
    token = strtok(color, " ,\n");          // test for space and newline
    while(token != NULL && i < 3) {         // test `i` too
        colord[i] = DecodeString(token);
        i++;
        token = strtok(NULL, " ,\n");       // test for space and newline
    }
}

Finally you should divide by 1000 when displaying kOhms.
