what you all people say ??

Answer 1

It will give output true

#include <stdio.h>
typedef int bool;
#define true 1
#define false 0
 
int main(void) {
	bool b= false ;
 
if(b = true) //here equal to is an assignment statement
 
printf("true"); // code come here and simply print true
 
else
 
printf("false");
 
	return 0;
}

import java.util.*;
import java.lang.*;
import java.io.*;
 
/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
	public static void main (String[] args) throws java.lang.Exception
	{
		Boolean b= false ;
 
if (b = true)
 
System.out.println("true");
 
else
 
System.out.println("false");
 
	}
}

Java is not C :)

okie i understood the logic :)

---

yes @sir but logic is same

---

No. Java is a type safe language - we cannot use "int" in place of Boolean in Java as in C. So, the given code should give compile error in Java.

---

ok done in java too :)

No need of int here

So, answer will be same

yes you are right,

the assignment oeprator will work same and it will print true

right:)
