Find the Day 5 Loops Hackerrank Solution in C language. day 5 problem is dedicated to “Loop” in programming, we need to perform a task using “Loop”, as we all know there are basically 4 types of “Loop” in programming, first one is For Loop, the second one is While Loop(Whlie-Do Loop), and the third one is Do-While Loop.
There is one more loop which is For-Each(Used in Java Programming) loop to know more about the visit to Stackoverflow, now come to the point we also have to find the Loops Hackerrank Solution in Java, C++, and C Programming languages.
Day 5 Problem Statement
Given an integer,n, print its first 10 multiples. Each multiple n * i (where 1<=i<=10) should be printed on a new line in the form: n x i = result.
Input Format
A single integer, n.
Constraints
2<=n<=20
Output Format
Print 10 lines of output; each line i(where 1<=i<=10) contains the result of n * i in the form: n x i = result.
Sample Input
2
Sample Output
2 x 1 = 2 2 x 2 = 4 2 x 3 = 6 2 x 4 = 8 2 x 5 = 10 2 x 6 = 12 2 x 7 = 14 2 x 8 = 16 2 x 9 = 18 2 x 10 = 20
For Loop Syntax
Code Explanation
Here n is an integer number we have to print the table of n, first take user input and store the value in ‘n’. after that use a ‘for loop’ and put the three conditions in ‘for loop’. Below is a for-loop syntax.
So according to the above syntax take a user input, initialize the loop with i = 0 and put the condition i <= 10 and the last condition is i++ or i =i+1. And multiplication i and n and printing the result is according to the problem statement.
for(initialization ; condition ; increament / decreament)
