What is/are the difference of the two? Why they have different output?

Question

in C++
cout<<'h'<<'i';
Output is: hi

But in Java
System.out.print('h'+'i');
Output is: 209

I am confused

Answer 1

In both C++ and Java:
'h'+'i'
is 209 as 'h' is 104 and 'i' is 105.
cout << 'h'+'i'; // outputs 209.

Answer 2

This is bcoz of ASCII values since computer does not understand characters and in Java we need to use " " for printing characters.

Answer 3

Your C++ code prints two characters. The equivalent Java is:
System.out.print('h');
System.out.print('i');

Answer 4

Make a string.
""+'h'+'i'
will make "hi" in both languages. Also:
"h"+"i"
will do it in both languages.

Answer 5

Because each << operator makes a separate print call.

Answer 6

You are welcome.

Answer 7

Ahh ok, tnx a lot 😇

Answer 8

In 1st thing with C++ you just print to chars to console. But in 2nd with java you perform a char concatenation which is actually an addition of values of the 2 char values.

Answer 10

Why I tried to compile cout<<'h'<<'i'; in c++ the out is "hi"?

Answer 11

So how can I concatenate two characters in c++ that the output is like in java?

Answer 12

Nice
Ok

Answer 13

in both languages 'h' + 'i' is 209, because it's the sum of the ascii values
if u use cout << 'h' + 'i'; in c++ it would also output 209

cout << 'h' << 'i'; is like cout << 'h'; cout << 'i';
which would be the java equivalent of System.out.print('h'); System.out.print('i');

Answer 14
