2) Which is an infinite loop? a. loopCount = 1; while(loopCount < 3); { System.out.println("Hello"); loopCount = loopCount + 1; } b. loopCount = 5; while(loopCount > 3); { System.out.println("Hello"); loopCount = loopCount - 1; } c. loopCount = 4; while(loopCount < 3); { System.out.println("Hello"); loopCount = loopCount + 1; } d. loopCount = 1; while(loopCount < 3); { System.out.println("Hello"); }
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.
1) Provided the following userNum input values, how many times would the loop body execute? if (userNum >= 0) 9 4 3 0 -2 /Do something..... /Obtain userNum from the input
a. 3
b. 4
c. 5
2) Which is an infinite loop?
a. loopCount = 1;
while(loopCount < 3);
{
System.out.println("Hello");
loopCount = loopCount + 1;
}
b. loopCount = 5;
while(loopCount > 3);
{
System.out.println("Hello");
loopCount = loopCount - 1;
}
c. loopCount = 4;
while(loopCount < 3);
{
System.out.println("Hello");
loopCount = loopCount + 1;
}
d. loopCount = 1;
while(loopCount < 3);
{
System.out.println("Hello");
}
d. 6
