Your code won't even compile in any compiler that you have mentioned above.
What's your actual compiler? Both C++ and Java cannot be your target

I use netbeans, Netbeans does not use standard javac

Mohibur Rashid 26-Nov-18 23:54pm

So, what non-standard java are you using and if it is not standard java then why tagging java or even c++?

I am asking this question to help you, not to judge you.

Solution 3

You really don't need if statements:

Java

public static void main(String arg[])
 {
   for (int r = 0; r < 10; ++r)
   {
     for (int c = 0; c < 10; ++c)
       System.out.print('X');
     System.out.println();
   }
 }

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

The debugger is here to only show you what your code is doing and your task is to compare with what it should do.

Solution 2

You must code

C++

System.out.print("x");

if(column == 10){
  System.out.print("\n");//print newline

What about learn to code and debug?
