What is wrong with it? This example from Head First C, does not run as it should be. I've tested every part but I jus't can't it figure out

Question

#include <stdio.h>

#include <string.h>

char tracks[][80] = {
    "I left my heart in Harvard Med School",
    "Newark, Newark - a wonderful town",
    "Dancing with a Dork",
    "From here to maternity",
    "The girl from Iwo Jima",
};

void find_track(char search_for[]) {

  int i;

  for (i = 0; i < 5; i++) {

    if (strstr(tracks[i], search_for))

      printf("Track %i: '%s'\n", i, tracks[i]);
  }
}

int main() {

  char search_for[80];

  printf("Search for: ");

  fgets(search_for, 80, stdin);

  find_track(search_for);

  return 0;
}

Answer 1

The function fgets can append the entered string with the new line character '\n'.

You need to remove it as for example

fgets(search_for, 80, stdin);
search_for[ strcspn( search_for, "\n" ) ] = '\0';
