C program to print first n even natural numbers; Through this tutorial, we will learn how to print first n (10, 100, 1000 .. N) even natural numbers in the c program with the help for loop and while loop
Algorithm and Program to Print First N Even Natural Numbers in C
Use the following algorithm and program to print first n (10, 100, 1000 .. N) even natural numbers in C:
- Algorithm to Print First N Even Natural Numbers
- C Program to Print First N Even Natural Numbers using For Loop
- C Program to Print First N Even Natural Numbers using While Loop
Algorithm to Print First N Even Natural Numbers
Use the following algorithm to write a program to find and print first n(10, 100, 1000 .. N) even natural numbers; as follows:
- Step 1: Start Program.
- Step 2: Read the a number from user and store it in a variable.
- Step 3: Find first n even natural number using for loop or while loop.
- Step 4: Print first n even natural number.
- Step 5: Stop Program.
C Program to Print First N Even Natural Numbers using For Loop
#include <stdio.h>
void main()
{
int i,n;
printf("Input number of terms : ");
scanf("%d",&n);
printf("\nThe even numbers are :");
for(i=1;i<=n;i++)
{
printf("%d ",2*i);
}
}
The output of the above c program; as follows:
Input number of terms : 5 The even numbers are :2 4 6 8 10
C Program to Print First N Even Natural Numbers using While Loop
#include <stdio.h>
void main()
{
int i,n;
printf("Input number of terms : ");
scanf("%d",&n);
printf("\nThe even numbers are :");
i = 1;
while (i <= n)
{
printf("%d ", 2 * i);
i++;
}
}
The output of the above c program; as follows:
Input number of terms : 5 The even numbers are :2 4 6 8 10
