## C Program to print Even numbers till N

### Description

```Get input n and print even numbers till n.
Input:
7
Output:
2 4 6```

### Solution

```#include<stdio.h>
int main()
{
int n,i;
printf("Enter a number:");
scanf("%d",&n);
printf("Even numbers till %d:\n",n);
for(i=0;i<=n;i=i+2)
{
printf("%d ",i);
}
return 0;
}```

### 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.```
