Hey guys I can get this to compile, but the results should come back as 0 or 1 but if i try to output the results of c1 or c2, I get -44 or 8, which does not make sense. What might be wrong with this statement:
Code:for( int i=0; i<36; i++){
int c1=0;
int c2=0;
//compares user locations with the input file
c1= strncmp(userLocA, b[index].getLocationOne(),strlen(userLocA));
c2 = strncmp(userLocB, b[index].getLocationTwo(),strlen(userLocB));
if(c1==0 && c2==0)
break;
}
Quote:
Declaration:
int strncmp(const char *str1, const char *str2, size_t n);
Compares at most the first n bytes of str1 and str2. Stops comparing after the null character.
Returns zero if the first n bytes (or null terminated length) of str1 and str2 are equal. Returns less than zero or greater than zero if str1 is less than or greater than str2 respectively.
> c1= strncmp(userLocA, b[index].getLocationOne(),strlen(userLocA));
Maybe this should be i?
c1= strncmp(userLocA, b[i].getLocationOne(),strlen(userLocA));
The Dog You have to excuse me I am a little new at this can you help me apply this to my function?
Swoopy, no I have index from earlier in my program its a string I need to compare from an input file stored in b which is a class i created

The return value of strncmp() could be a negative number ( < 0 ), or 0, or a positive number ( > 0 ).

Therefore "-44" shows that the string is less than, and "8" shows that the string is more than.
Print the string that you are comparing before you compare them.
