Hi.

This is NOT a homework assignment (self-interest only).

The exercise asks me to write a function which accepts two strings and returns a pointer to the longer of the two.

[code language="C"]
#include <stdio.h>
#include <stdlib.h>

char* longer( char str1[], char str2[] );
char* str_ptr;

int main( void ) {

char str1[] = "I like cheese but I dislike brussel sprouts!";
char str2[] = "I like cheese and pasta!";

str_ptr = longer( str1, str2 );

printf( "The longer string is: %s\n", str_ptr );

return 0;
}

char* longer( char str1[], char str2[] ) {

int i = 0, count1 = 0, count2 = 0;

while( str1[i] != NULL ) {
i++;
count1++;
}

while( str2[i] != NULL ) {
i++;
count2++;
}

if( count1 < count2 )
return str2;
else if ( count1 > count2 )
return str1;
else
puts( "The strings are of equal length!" );
}
[/code]

The compiler returns the following warnings:

ex106.c: In function `longer':
ex106.c:23: warning: comparison between pointer and integer
ex106.c:28: warning: comparison between pointer and integer

I'm unsure of how exactly to resolve the problems but am I correct in assuming it is a result of using an index on the str1 and str2 arrays?

Thanks,
