The following code provides a solution for printing a sequence of values using a for loop in C++. This code demonstrates a simple yet effective way to print a series of numbers that follow a specific pattern, in this case, the sequence of odd numbers from 1 to 13.
Which Compiler is best?
- For Laptop, Offline or PC Devices use Visual Studio Code or CFree , Dev C++.
- For Mobile Devices you can use online Compilers such as w3shools.
Code Elements:
<iostream> Library:
The code begins by including the iostream
library, which provides functions for input and output operations..
cout command:
We will use cout commands to print our output on the screen.
Loop Statement:
he main function is then defined and inside the main function, we have a while loop. The while loop is used to iterate over a range of values, in this case, the range of odd numbers from 1 to 13.
Compound Operator:
Compound Operators like +=, *= is used to add and multiply values directly into the variable;
Final Coding:
Now we will write the final code :
1- Library
We are using iostream library and int main body.
#include <iostream>
using namespace std;
int main () {
}
2- Declaring Variables
int _x = 1;
3- Using While Loop
The loop initializes a variable i
to 1 and sets the termination condition to i <= 13
. This means that the loop will run until i
becomes greater than 13. The increment expression i += 2
updates the value of i
by adding 2 in each iteration, thus making it an odd number.
while(_x<=13)
{
cout<<_x <<endl;
_x+=2;
}
Inside the loop, the cout
function is used to print the value of i
on the screen. The cout
function writes the output to the standard output stream, which is usually the screen. The <<
operator is used to concatenate the value of i
with the space character to separate each number in the sequence.
Finally, the endl
function is used to insert a newline character, which causes the program to print each number on a separate line. The return 0
statement at the end of the main function is used to indicate that the program has completed successfully.
In conclusion, this code provides a simple and efficient way to print a sequence of values using a for loop in C++. The for loop is a powerful construct that can be used to iterate over a range of values, and in this case, it makes it easy to print the desired sequence of odd numbers.
