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.
Fill-in-the-Blank
A loop that does not have a way of stopping is a(n) __________ loop.

Follow each number with a space. After the loop, print a newline. Ex: If numInsects = 16, print:16 32 64 128 C++ #include <iostream>using namespace std; int main() { int numInsects; cin >> numInsects; // Must be >= 1 /* Your solution goes here */ return 0;}L E S S O N S E T5 Loops and Files Working with the while LoopBring in program while.cpp from the Lab 5 folder.

- C++ please! Write code with one while loop that prints out these 5 lines like this (remember a newline after each line): COUNTDOWN TO ZERO: 4 COUNTDOWN TO ZERO: 3 COUNTDOWN TO ZERO: 2 COUNTDOWN TO ZERO: 1 COUNTDOWN TO ZERO: LIFT OFF!An insect population doubles every generation. Write a while loop that iterates numGeneration times. Inside the while loop, write a statement that doubles currentPopulation in each iteration of the while loop.Integer numInput is read from input. Write a while loop that reads integers from input until an integer that is greater than or equal to 1 is read. Then, find the sum of all integers read. The integer greater than or equal to 1 should not be included in the sum. Ex: If the input is -15 -9 -2 -39 41, then the output is: -65 #include <iostream> using namespace std; int main() { int numInput; int sum; sum = 0; cin >> numInput; /* Your code goes here */ cout << sum << endl; return 0; }
- 1. In the first loop, the low number will be the starting point for the loop and thehigh will be the ending point. The loop should display the iterator number andthat number x 10 on the same line, separated by a tab. See example on p. 177.2. The second loop should accumulate all the numbers between the starting pointand ending point. You will need to create and initialize an accumulator such astotal before you start the loop.Writing a while loop Write a while loop that continues to increment userValue by 5 as long as userValue is less than 0. Please make sure rightComplete lines of code so the do while loop will execute and produce the output shown here. The output is: Time for fun!
