How to wrap a line in the output?

# Include <stdio. h>
Void main ()
{
Int I, n;
Int a [500] = {0 };
For (I = 1; I <500; I ++) a [I] = a [I-1] + 1;
For (I = 0; I <500; I ++)
{
If (a [I] % 5 = 0)
{
Printf ("% d", a [I]);
N ++;
If (n % 5 = 0) printf ("\ n ");
}
}

}
The line feed of C ++ is just now. This is C.

2. Use a java program to list the first 20 numbers. Each line needs to output 5 numbers before line feed.

Public class Example
{
Public static void main (String args [])
{
String output = "";

For (int I = 1; I <= 20; I ++)
{
If (I % 5 = 0)
{
Output + = I + "\ n ";
}
Else
Output + = I + "\ t ";
}
System. out. println (output );
}
}
