Exercise $5$: Search in an array with pointers

$($a$)$ Wrire the following function:

int search$($int $a[],$ int $n,$ int key$)$

$a$ is an array to be searched, $n$ is the number of elements in the array, and key is the key being searched. search

should return TRUE $(1)$ if key matches some element of $a,$ FALSE $(0)$ if it doesn't. Use pointer arithmetic $-$ not

subscripting $-$ to visit array elements

$($b$)$ Assume that the following array contains a week's worth of hourly temperature readings, with each row containing

the readings for one day:

int temperatures$[7][24]$;

Write a function that uses the search function, defined in $($a$),$ to search the entire temperatures array for a value,

val, and returns the row in which it is found.

$($c$)$ Write a function that uses a loop to print all temperature readings stored in row $i$ of the temperatures array. Use a

pointer to visit each element of the row.

$($d$)$ Write a driver program to test all your functions.
