strrchr()

, strlen(), strcmp()

A pointer to the first match found, or NULL if the character does not exist in the string.

Although the function takes an integer argument for the character, only the lower 8 bits 
of the value are used.

#include <string.h>

 

int strcmp (const char * s1, const char * s2)

int stricmp (const char * s1, const char * s2)

The 

strcmp()

 function compares its two, null terminated, string arguments and returns 

a signed integer to indicate whether 

s1

 is less than, equal to or greater than 

s2

. The 

comparison is done with the standard collating sequence, which is that of the ASCII 
character set.

The 

stricmp()

 function is the case-insensitive version of this function.

#include <string.h>

#include <stdio.h>

main (void)

    int i;

    if((i = strcmp("ABC", "ABc")) < 0)

        printf("ABC is less than ABc\n");

    else if(i > 0)

        printf("ABC is greater than ABc\n");

    else

        printf("ABC is equal to ABc\n");
