Thread: Concatenation using system()

If anyone have any tips, here is the whole code:

Thanks again! =)

Code:

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

int main ()
{
  char var[9] = {0};
  char str[80];

  scanf( "%8s", &var );

  strcpy (str,"ren C:\\temp\\text.txt text");
  strcat (str, var );
  strcat (str,".txt");
  puts (str);
  system(str);
  system("pause");
  
  return 0;
}

You don't need the ampersand, since var is a character array var without the ampersand would be the address of the array.

Code:

 scanf( "%8s", &var );

When you are having problems the first thing you should look at is: Are your inputs correct? If you would print out the var variable after the scanf you would probably see a problem.
