Set RSIZE to $5.$ Set CSIZE to $7.$ Write a program that creates a matrix of RSIZE rows by CSIZE columns of numeric elements.$$ Write a nested for loop that stores the numbers from $1$ to RSIZE$*$CSIZE in the matrix.$$ After storing the values, calculate the sum of all the values in the array and display the sum.

Modify the program you wrote for Problem $1$ such that it adds a User given number to all elements of the matrix first, and then displays the sum of all elements.

Modify the program you wrote for Problem $2$ such that it multiplies a User given number to all elements of the matrix first, and then displays the sum of all elements.

Modify the program you wrote for Problem $3$ such that it exponentiates a User given power to all elements of the matrix first, and then displays the sum of all elements.

Modify the Program you wrote for Problem $4$ to ask the User for a row number.$$ Display the row number of the matrix.

Modify the Program you wrote for Problem $4$ to ask the User for a column number.$$ Display the column number of the matrix.

Modify the Program you wrote for Problem $4$ to ask the User for a row and a column number.$$ Display the element of the matrix.

Modify the Program you wrote for Problem $7$ to loop asking for a row and column number and displaying the element, until the user enters in $-1$ for the row number.
