if i make this same program in my laptop or computer then output coming is like a shape of heart..

Answer 1

I know buddy , when i was in school ... i tried printing some characters there , they were showing "?"(upside down) , while they show solid blocks here
//might thats the difference of output-playground here ,
👉see whole table from 1 to 256 here using a loop & then use those characters wisely

Answer 2

public class Program
{
public static void main(String[] args) {
char c,c1;
c= 3;
c1= c;
System.out.println("t"+c1+"t");
}
}

👉try this , what u notice between those two t's , some space ... right ?
//thats what c1 is

Answer 3

it is printing some space
//i know we can't see the space , therefore I putted two t's on both sides of the character it prints ... so we can see whether something is there or not ... ☝

Answer 4

@gaurav agrawal if i try this in computer then output shows like a shape of heart if u dont beleive this then u can also try this and @sara every character has an integer value.if u write 65 in place of 3 them u get output A...

Answer 5

because c and c1 do not have same data types .
c is integer and c1 is character.
you can not write char c,c1
you are saying both of them are characters but after that you put a number in c 😊
