Computer Science Chapter 4 and 5 True or False
False
The do while loop is a pretest loop
True
The for loop is a posttest loop
False
A variable defined in an inner block may not have the same name as a variable defined in the outer block
True
A variable may be defined in the initialization expression of a for loop
True
All lines in a block should be indented one level
True
In a nested loop, the break statement only interrupts the loop it is placed in
True
In a nested loop, the inner loop goes through all of its iterations for every single iteration of the outer loop
False
The = operator and the == operator perform the same operation when used in a Boolean expression
False
The break statement causes a loop to stop the current iteration and begin the next one
False
The cout statement in the following program segment will display 5: int x = 5; cout << ++x
True
The cout statement in the following program segment will display 5: int x = 5; cout << x++;
True
Variables may be defined inside the body of a loop
True
When an if statement is nested in the else part of another statement, as in an if/else if, the only time the inner if is executed is when the expression of the outer if is true
True
When an if statement is nested in the if part of another statement, the only time the inner if is executed is when the expression of the outer if is true
True
x != y is the same as (x>y || x<y)
False
x >= y is the same as (x > y && x =y)
False
y < x is the same as x >=y
True
A conditionally executed statement should be indented one level from the if statement
False
It is not necessary to initialize counter variables
False
It's safe to assume that all uninitialized variables automatically start with 0 as their value
False
One limitation of the for loop is that only one variable may be initialized in the initialization expression
False
The operand of the increment and decrement operators can be any valid mathematical expression
True
The scope of a variable is limited to the block in which it is defined
True
The while loop is a pretest loop
True
You can use the relational operators to compare string objects
