Write the function definition for zero_all. It sets all the values in its array parameter to zero. Write loops to do this.

Write the function definition for zero_row. It sets the values in its array parameter in the given row to zero. Write a loop to do this.

Make function calls as directed by the comments in main.

Run your program. The print function does not properly space the array when printed. Fix the program so that the array is printed properly in 2 dimensions.

Submit your completed Lab3.cpp C++ source file on Blackboard.

1. Explain clearly why it makes sense to put the linefeed in that particular spot in the print function where you placed it.

please take Screenshot of the output

2. Switch the order of the two loops in the initialize function (col loop first and then row loop) and run your program. Explain what changed in the output and why.

3. Just before the final print in main, add the following assignment statement:

rect [1][6] = 20;

Run your program. Explain what happened.
