How to get desired char output?

[SakuraPink]

I'm new to C and I have a question I think it's not that complicated. I'm trying to write a code that creates strings like : File1,File2,File3, etc.
Here is my code:

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

int main(void){

  char string1[80]="File";
  char string2[80]="";
  int number = 10;
  int i;

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

  sprintf (string2,"%d",i);
  strcat( string1, string2);
  printf("Characters: %s \n" ,  string1);
  char string1[80]="File";
  char string2[80]="";
  }
  return 0;

 }

But what I'm getting is File0,File01,File012,...

Could you please tell me how to solve this?

I have changed it to the following code and now it works!

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

int main(void){

  char string1[80]="File";
  char string2[80]="";
  int number = 10;
  int i;

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

  char string1[80]="File";
  sprintf (string2,"%d",i);
  strcat( string1, string2);
  printf("Characters: %s \n" ,  string1);
  // for(i=0;i<80;i++) {
  string1[0]='\0';
  string2[0]='\0';
  //}
  }
  return 0;

 }

Why are you redefining string1 and string2 in lines 18 & 19? Technically, the placement of these statements is illegal in C.

You strcat() to string1 but you never reset it's value back to "file".

Also, please learn to format your code[/url\. It's extremely important the larger your programs grow, and if you need help, formatting helps others read your code.
