1. Write a for statement to add all the multiples of 3 between 1 and 100.

2.How many times will each of the following loops execute? What is the output in each case?

a.

x=5;y=50; do

x = x + 10;

while (x < y);

cout << x << " " << y << endl;

x = 5; y = 80;

do

x = x * 2;

while (x < y);

cout << x << " " << y << endl;

b.

x = 5; y = 20; do

x = x + 2;

while (x >= y);

cout << x << " " << y << endl;

c.

x = 5; y = 35; while (x < y)

x = x + 10;

cout << x << " " << y << endl;
