array character to character

Code:

---

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

main()
{

const char *temp="hello";
const char *string="how";

          printf("%d",strcmp(temp[0],string[0])); 

}

---

The code gave me the following warning msg.

c:\documents and settings\winson\desktop\data structure\forum.c(10) : warning C4047: 'function' : 'const char *' differs in levels of indirection from 'const char '
c:\documents and settings\winson\desktop\data structure\forum.c(10) : warning C4024: 'strcmp' : different types for formal and actual parameter 1
c:\documents and settings\winson\desktop\data structure\forum.c(10) : warning C4047: 'function' : 'const char *' differs in levels of indirection from 'const char '
c:\documents and settings\winson\desktop\data structure\forum.c(10) : warning C4024: 'strcmp' : different types for formal and actual parameter 2

I would like to compare some of the character between two strings.

I would like to know how i can solved this problem. For your information, i would like the solution in C and not C++. Thanks

Code:

---

printf("%d",strcmp(&temp[0],&string[0]));

---

or simply

Code:

---

printf("%d",strcmp(temp,string));

temp[0] and string[0] are single char's, they are not pointer to const char. That is why you are getting the warning. You would note that this won't give you a warning.

Code:

---

printf("%d",strcmp(temp, string));

---

Note the difference?

Code:

if ( temp[0] == string[0] )

You compare char's just like you compare int's, float's, long's or double's -- use ==.

If you want to compare an array of char with another array of char, then you must either write code that compares character by character, or use a function such as strcmp() or memcmp().
