PRINT FIRST 'N' EVEN NUMBER WITH WHILE STATEMENT.

Write a program to print first ‘n’ even number.

For this program I’m using while statement to run the loop. While is an repetition  statement which is used to run the program again and again until the required statement is satisfied.

Syntax:  -

While (condition)

{

.

.

Statement ;

.

}

Program: -

#include<stdio.h>

void main()

{

int n, a=2, i=0;

clrscr();

printf("\n how many first even number you want to calculate=");

scanf("%d", &n);

while(i<n)

{

printf("\n %d", a);

a=a+2;

i++;

}

getch();

}

Output: -

How many first even number you want to calculate=
