Answer 2

Catafrancia Mapper [ School ] Here is Java. I'm not sure if there is a cleaner way to do this in Java. This is the way I know of.

Answer 3

Why exactly do you need to do this in so many languages? Is it just for learning?

Answer 4

You can *auto* keyword in C++ for that purpose.

Example :-

#include<iostream>
int main()
{
auto a = 57;
auto b = "hello"
std::cout<<a<<"\n"<<b;
}

Output :-

57
hello

Answer 18

C, C#, and Java(v. 1 - 9):
<data type> <variable>;
<data type> <variable> = <expression>;

C++:
auto <variable> = <expression>;
<data type> <variable>;
<data type> <variable> = <expression>;

Java(v. 10+):
var <variable> = <expression>;
<data type> <variable>;
<data type> <variable> = <expression>;

Kotlin:
var <variable> : <data type>;
var <variable> : <data type> = <expression>;
val <variable> : <data type> = <expression>;
var <variable> = <expression>;
val <variable> = <expression>;

PHP(v. 1 - 4):
<dollar sign(s)> <variable> = <expression>;

PHP(v. 5+):
<data type> <dollar sign(s)> <variable> = <expression>;
<dollar sign(s)> <variable> = <expression>;

Answer 19

So ... input must contain backslash like that? ☝

Hello \(world)

And <world> is a variable defined in code right? not user input? (I haven't learned Swift yet)

(Edit)
In PHP it's easy, given the string is wrapped in double quotes, variables will expand to their respective value. No backslash nor $ sign is necessary. One drawback I noticed though, PHP doesn't process expressions, so if we have an expression a + b * c, we can't put it as is, instead the expression result needs to be stored into a variable, which will be embedded in the string (cmiiw).

I wanted to write in Dart also but found Solo Learn Doesn't have this support. But JavaScript rocks. Take a look...
