Thread: StrCmp

Can someone show me what StrCmp looks like written out?

This was taken from the help file from my compiler : Borland c++ 5.02

Code:

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

int main(void)
{
    char *buf1 = "aaa", *buf2 = "bbb", *buf3 = "ccc";
    int ptr;

    ptr = strcmp(buf2, buf1);
    if (ptr > 0)
        printf("buffer 2 is greater than buffer 1\n");
    else
        printf("buffer 2 is less than buffer 1\n");

    ptr = strcmp(buf2, buf3);
    if (ptr > 0)
        printf("buffer 2 is greater than buffer 3\n");
    else
        printf("buffer 2 is less than buffer 3\n");

    return 0;
}

theres also an "strcmpi" that compares without case sensitivity

theres also an "strcmpi" that compares without case sensitivity

Its not compaticle with ANSI i guess its a borland function ??

No I mean the function itself not using it.

i think he means like whats string compare doing??????

From K&R2

Code:

/* strcmp:  return <0 if s<t, 0 if s==t, >0 if s>t */
int strcmp(char *s, char *t)   
{      
    for ( ; *s == *t; s++, t++)
           if (*s == '\0') return 0;
    return *s - *t;   
}
