What is the name of loop variable, or loop control variable? How many iterations does the loop do? What is initial value of count?
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.
please answer all questions about for loop below:
for (i = 1; i <= 5; i++)
{
cout << i << “, ”<<endl;
}
Questions:
- What is the name of loop variable, or loop control variable?
- How many iterations does the loop do?
- What is initial value of count?
- What is value of i when the loop exits (fails)
- What is the output of the code?
- What is increment in i between each iteration
- Observe comma in cout
- When is the variable incremented: Beginning or the end
- Loop variable must be defined before entering loop
- This is pretest loop
The integer counter, i, controls the number of loop iterations
