here is my code
Code:
#include <stdio.h>

#define MAX 81



void substring(char *n,int i,int j)
{int k;
char substr[MAX];
   for(k=0;k<=j;k++)
   {
   printf("%c",*(n+i+k));
   *substr=*(n+k+i);
   substr++;


}
*substr='\0';
printf("%s",substr);
}
int main(void)
{

    char name[MAX];  /* allot space                  */



    printf("Hi, what's your name?\n");

    gets(name);      /* place string into name array */

    printf("Nice name, %s.\n", name);

substring(name,2,1);


    return 0;

}
its giving an error "error: wrong type argument to increment"

i think i am doing right but still getting error .please someone suggest something
