Exercise 5.4. Write the function strend(s,t), which returns 1 if the string t occurs at the end of the string s, and zero otherwise.

/* strend */

int strend(char *s, char *t)

{

    char tmps = *s;

    char tmpt = *t;

    while(*s)

        s++;

    while(*t)

        t++;

    while(*s == *t)

    {

        if(*s == tmps || *t == tmpt)

            break;

        s--;

        t--;

    }

    if(*s == *t && *t == tmpt && *s != '\0')

        return 1;

    else

        return 0;
