What is printed by each of the following? Assume that all variables are declared as int.
1. i = 1; 2. i = 2;
while (i < 10) while (i < 10)
i = i + 1; i++;
cout << i << endl; cout << i << endl;
3. i = 10; 4. i = 2;
while (i < 10) while (i < 15)
i = i + 1; i = i + 2;
cout << i << endl; cout << i << endl;
5. total = 4;
i = 2;
while (i < 5)
{
total = total * i;
i = i + 1;
}
cout << "The total is " << total << endl;
6. i = 0; 7. i = 0;
while (i < 5) if (i < 5)
{ {
cout << i << endl; cout << i << endl;
i = i + 1; i = i + 1;
} }
8. i = 15; 9. a = 3;
while ( i == 25) b = 100;
{ while (b / a > 5)
cout << i << endl; if (b - a > 90)
i = i + 1; {
} a = a + 5;
cout << a << endl;
}
else
{
b = b / 2;
cout << b << endl;
}
10. Use a while loop to write a program segment that:
1. reads a number input by the user and stores the number in a
variable called limit.
2. prints all the odd numbers between 1 and limit
11. Use a while loop to write a program segment that:
1. reads a number input by the user and stores the number in a
variable called limit.
2. adds up all the numbers between 1 and limit
3. prints the sum

Remember to type your answers and to make two copies of each homework assignment. One copy is submitted to me and the other you keep to use in the group discussions.
