Hello guys this is my second question and it is quit foolish of me, but I am not getting it so please help me.
In the following program I know the output but I am confused how it is done.
Program 1

XML

#include<stdio.h>
#include<conio.h>
main()
{
      int x=2;
      if(x=3)
      {
      printf("%d",x++);
      }
      else
      {
      printf("%d",--x);
      }
getch();
}

The output of the following program is 3 but how it comes, I don't get it.

Program 2

XML

#include<stdio.h>
#include<conio.h>
int main()
{
      int x=01234;
      printf("The result is  %d",x);
      return 0;
      getch();
}

The Output of the following program is 668 and don't get it too.
So please give me some hint.

Thanks guys...:)

In the program 1 the x=3 assignment is hidden inside the if statement. It is a common mistake by the programmers to use assignment (=) operator in place of equal (==) operator.

In the program 2, when you assign a value to variable x you use an octal form (when a numeric literal begins with 0 it is an octal number)

Solution 1

This is realy a bad question. For what purpose the code is write? Are you test members in Code project? Listen program1, there is no comparison in if condition. ie, watch your code

C++

if( x = 3 )

. Actualy here value 3 is assigned to x. no comparison is done.
Don't post this type of question in code project. You can debug the code and ensure what happend.
