C Program to print Even numbers till N

Get input n and print even numbers till n.

Sample Input 1:


Sample Output 1:

2 4 6

Program or Solution

int main()
	int n,i;
	printf("Enter a number:");
	printf("Even numbers till %d:\n",n);
		printf("%d ",i);
	return 0;

Program Explanation

Instruction(s) inside the for block{} are executed repeatedly till the second expression (i<=n) is true.

Here i is initialized to 2 and incremented by 2 for each iteration, instructions inside the for block are executed unless i becomes greater than n.

so value of i will be printed like 2 4 6 .... (n-1) or n using printf statement.
