Which is true about a do...while loop?
Body of loop executes at least once
Which doesn't have an entry condition?
do...while
Which loop is guaranteed to execute at least once
do...while
A break statements is legal in in a while loop, but not in a for loop
false
A loop that continues to execute endlessly is called an endless loop
false
A syntax error will result if the control statements of a for loop are omitted
false
A while loop is a post test loop
false
Because a do...while loop is a post test loop, the body of the loop may not execute at all
false
EOF-controlled while loop is another name for sentinel-controlled while loop
false
If the while expression becomes false in the middle of the while loop body, the loop terminates immediately
false
In the for statement, if the logical expression is omitted, it is assumed to be false
false
Like a do...while loop, the body of a while loop executes at least once
false
control variables are automatically initialized in a loop
false
order for the for loops is
initial expression, logical expression, update expression
Which of the following is not a reserved word in java?
loop
which executes first in a do...while loop?
statement
Which is not a function of the break statement
to ignore certain values for the variables and continue with the next irritation of a loop
A counter controlled loop is used when the exact number of data entries is known
true
A loop is a control structure that causes certain statements to be executed over and over until certain conditions are met
true
After a break statement executes, the program continues to execute with the first statement after the structure
true
If a continue statement is placed in a do...while structure, the loop-continue is evaluated immediately after the continue statement
true
In the case of an infinite while loop, the while expression (that is the loop condition) is always true
true
In the case of the sentinel-controlled while loop, the first item is read before the while loop is entered
true
In the case of the sentinel-controlled while loop, the first term is read before the while loop is entered
true
The control statements in the for loop include the initial expression, logical expression, and update expression
true
The do...while loop has an exit condition but no entry condition
true
The loop condition of a while loop is reevaluated before every iteration of the loop
true
To read data from a file of unspecified length, an EOF-controlled while loop is a better choice than a counter-controlled while loop
true
