1Why should you be careful when choosing a sentinel value? 2In the following program segment, which variable is the loop control variable (also known as the counter variable) and which is the accumulator? int num, num1 = 0, num2 = 0; Loop Control Variable: _____________________ Scanner keyboard = new Scanner(System.in); while (num1 < 10) { Accumulator: _____________________ System.out.print("Enter a number: "); num = keyboard.nextInt(); num2 += num; } System.out.println("The sum is " + num2); 3Correct the errors in the following code segment. // This code contains ERRORS! // Print the numbers 1 through 10. for (int count = 1, count <= 10, count++;) { System.out.println(count); count++; } please solve three of them
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.

- 2In the following
program segment, which variable is the loop control variable (also known as the counter variable) and which is the accumulator?
int num, num1 = 0, num2 = 0; Loop Control Variable: _____________________
Scanner keyboard = new Scanner(System.in);
while (num1 < 10) { Accumulator: _____________________
System.out.print("Enter a number: ");
num = keyboard.nextInt();
num2 += num;
}
System.out.println("The sum is " + num2);
- 3Correct the errors in the following code segment.
// This code contains ERRORS!
// Print the numbers 1 through 10.
for (int count = 1, count <= 10, count++;) {
System.out.println(count); count++;
}
