C Program : Example

The following example shows the usage of abort() function.

#include<stdio.h>
#include<stdlib.h>
int main ()
{
   FILE *fp;
   printf("Open non-existing file in read mode");
   fp = fopen( "invisible.txt","r" );
   if(fp == NULL)
   {
      printf("File does not exists\n");
      abort();
   }
   printf("Close the file\n");
   fclose(fp);
   return(0);
}

In this case we don’t have invisible.txt file present in the directory so when we compile the above program then output of the program will be like this -

Open non-existing file in read mode
File does not exists
