Answer True or False _____ 1. It is possible that the body of a while loop might not execute at all. _____ 2. Control structures alter the normal flow of control. _____ 3. The result of a logical expression cannot be assigned to an int variable.
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
Answer True or False
_____ 1. It is possible that the body of a while loop might not execute at all.
_____ 2. Control structures alter the normal flow of control.
_____ 3. The result of a logical expression cannot be assigned to an int variable.
_____ 4. Every if statement must have a corresponding else.
_____ 5. The expression ! (x > 0) is true only if x is a negative number.
_____ 6. The while loop:
j = 0;
while (j <= 10)
j++;
terminates when j > 10.
_____ 7. A loop is a control structure that causes certain statements to execute over and over.
_____ 8. When a while loop terminates, the control first goes back to the statement just before the
while statement, and then the control goes to the statement immediately following the
while loop.
_____ 9. In a do…while loop, the condition is checked at the bottom of the loop.
_____ 10. A do…while loop may never execute.
