Characters are read until either a newline or an EOF is received or until the specified limit is reached.

You should use feof() or ferror() to determine what has actually happened.

Use fgets() to display the contents of the text file.

#include <stdio.h>
  #include <stdlib.h>

  int main(int argc, char *argv[])
  {
    FILE *fp;
    char str[128];

    if((fp=fopen("test", "r"))==NULL) {
      printf("Cannot open file.\n");
      exit(1);
    }

    while(!feof(fp)) {
      if(fgets(str, 126, fp)) printf("%s", str);
    }

    fclose(fp);

    return 0;
  }
