Write a C++ program without using arrays that ask a user to input values for an N x M dimension matrix. Such a matrix should have N x M values. Your program asks a user to first input the size of N and M, and then ask the user to input the values,

for example,

Please enter the value of entry [0,0]

Please enter the value of entry [0,1]

Each time the user enters a value, output the maximum, minimum, sum, average of the values entered so far.
