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);

You return after examining the first char, no matter how it turns out.

I think you missed the ; at the end of the for statement.

To the original poster, this is one reason why many recommend
for ( )
;

Rethink your logic.

}

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;
}
