Thread: string compare “EXC_BAD_ACCESS”.

this code

Code:

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

int main(){
	char *str1 = "A";
	char *str2 = "A";
	char *str3 = "!";
	
	printf("\n str1  =  %s", str1);
	printf("\n str2  =  %s", str2);
	printf("\n str3  =  %s", str3);
	
	printf("\nstrcmp(str1, str2) = %d", strcmp(str1, str2));
	printf("\nstrcmp(str1, str3) = %d", strcmp(str1, str3));
	printf("\nstrcmp(str3, str1) = %d", strcmp(str3, str1));
	
	if (strcmp(str1,str2) == 0) {
		printf("\n%s is equal to %s", str1, str2);
	}//if
	
	if (strcmp(str1, str3) > 0) {
		printf("\n%s is greater than %s", str1, str3);
	}//if
	
	if (strcmp(str3, str1 < 0)) {
		printf("%s is less than %s", str3, str1);
	}//if
	
	return 0;
}//main

gives this output:

Code:

 str1  =  A
 str2  =  A
 str3  =  !
strcmp(str1, str2) = 0
strcmp(str1, str3) = 32
strcmp(str3, str1) = -32
A is equal to A

the second "if" statement is not reached and I am unsure why?

You have "str1 < 0" as the second argument to strcmp, which is a bad thing.

rats!

ok, thanks.
