Write a while loop fragment that calculates the following values:a) Sum of the first n counting numbers: 1 + 2 + 3 + ... + nb) Sum of the first n odd numbers: 1 + 3 + 5 + ... + 2n - 1c) Sum of a series of numbers entered by the user until the value 999 isentered. Note: 999 should not be part of the sum.d) The number of times a whole number n can be divided by 2 (usinginteger division) before reaching 1 (i.e., log2n).
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.
Write a while loop fragment that calculates the following values:
a) Sum of the first n counting numbers: 1 + 2 + 3 + ... + n
b) Sum of the first n odd numbers: 1 + 3 + 5 + ... + 2n - 1
c) Sum of a series of numbers entered by the user until the value 999 is
entered. Note: 999 should not be part of the sum.
d) The number of times a whole number n can be divided by 2 (using
integer division) before reaching 1 (i.e., log2n).
