By using C$++$ pointer, write a C$++$ program to find the minimum element of an integer array. In main $()$ function, you declare and initialize an integer array. Then your will use a function $($int $*$findMin$($int arr$[],$int n$)$;$)$ that accepts the integer array and its size to find minimum number in the array. The return type from the function is the pointer that points to the minimum element in the array. You call this function from main$()$ and output minimum number in main$().$

S is one$-$dimensional array of integers. Write a C$++$ function to search for an element in array S which is smaller than integer num by using for loop. Use integer num and array as two parameters of your function $($ int$*$ searchsmall$($int$,$ int $[$MAXELS$])$; $).$ If the element which is smaller than num is found in the array then the function should return the pointer that points to that element in the array, otherwise returning NULL. Call this function from main$()$ function and output your result.
