Thread: please help me with this files program

Please give me code for the following :
The program should take one file as input which contains integers and should take it into a int variable. lets say, print that variable on the screen.

I wrote the following code but its showing errors..

Code:

# include <stdio.h>

int main (int argc, int argv[1] )
{
FILE *file_num ;
int num ;

file_num = fopen (argv[1],"r");
  if (!file_num) 
  printf ("File not found\n");
fscanf (file_num,"%d",&num);
printf("%d",num);
return ;
}

The programming is functioning when I replace these int types with char type but I need integers not characters.
