Labsheet1

Ni labsheet untuk Data Structure & Algorithm. Aku letak kat sini untuk share ngan sesape yang perlukan je. Kalau just nak copy and paste pun xde hal. Itu hal korang la. Aku harapkan feedback yang leh kita kongsi sama-sama..

Try to understand...
Jangan just nak ambik je. Aku xrugi.....

/*1.     Write a program which prints the characters in a cstring
        in reverse order.

    // ADD YOUR OWN CODE


#include

void main (){
    char s[10] = "abcdefgh";
    char* cptr;

    printf("Characters is %s\n",s);
   printf("Reverse order: ");

    cptr = &s[i];
    printf("%c",*cptr);

/*2.    Write a program with a function that returns a pointer to the
