CST$-210$ Topic $1$ Lab Question $3$

$($Week $3)$

The purpose of this lab is to practice the following:

Pointer arithmetic and array manipulation.

Finish the following program by adding a loop that uses only the pointer variable arrPtr to print the elements in the array arr.

srand$($time$($NULL$))$;

int arr$[10]$;

arr$[i]=$rand$()\%20$;

$3$

$//$print the array using the array name

for $($int $i=0$;$i<mn\; id="EditorElement\_389102">1</mn><mn\; id="EditorElement\_389103">0</mn>$;$i++)$

std::printf$("\%$d wi arr$[$i$])$;

$\}$

std: : cout $$ std:;endt;

$//$print the array using only the pointer arrptr

$//$HINT: look up pointer arithmetic

int$*$ arrPtr;
