int rows, columns;

for(rows = 0; rows < MAX_ROWS; rows++)

for(columns = 0; columns < MAX_COLS; columns++)

sum += rows + columns;

cout << "Value of sum is " << sum << endl;

1. How many times does the outer loop execute?

2. How many times does the inner loop execute?

3. What is the value of sum printed by cout ?

4. What would happen if you changed rows++ and columns++ to ++rows and ++columns ?

1. The outer loop will execute 5 times.

2. the inner loop will execute 6 times

3. the value printed by cout is 175
