(Sorry if this gets posted twice)
Hi all. I am trying to learn C.As a simple exercise i tried to write a
code which would compare two strings using pointers.
However i am not getting the correct result.
On tracing the program i noticed that the strings "s" and "t" get
modified somehow in the comp function and as a result i am getting
incorrect results.
Can anyone please point out the error?

#include<stdio.h>

int comp(char *s,char *t)
{
for(;*s==*t;s++,t++);
if(*s=='\0')
return 0;
else
return (*s -*t);

}

int main(void)
{
char str[]="Hello";
char str2[]="Hello";

if(comp(str,str2)!=0)
printf("strings are different");
else
printf("strings are same");
return 0;
