 Q1: write a program in c++ using  pointer with array to read a[5] and  “print” ,”inverted “ ,”summation” ,”average” arrays? Q2: write program to reads matrix of D[3][3] then use three functions , reset -> to reset main diagonal & secondry diagonal to zeros , [print -> to print array element values]?   Q3: {1,2,3,4,5,6}  ->  {1,3,6,10,15,21} use pointer?
