.exe

.exe is a programming language that takes a .exe file as its source code. So technically, you could say that you coded Minecraft using .exe.

Code execution

Jokes on you, it just runs the .exe file.

So, to write a program, do it in any other language you want.

Examples

Hello, World!

A Hello, World! program can pretty much be written with any language you want. Here are some examples:

Python

print("Hello, World!")

C

#include <stdio.h>

int main() {
   printf("Hello, World!");
   return 0;
}

C++

#include <iostream>

int main() {
    std::cout << "Hello, World!";
    return 0;
} 

Javascript

function main() {
    console.log("Hello, World!");
}

A+B problem

The A+B problem is a popular problem which takes 2 numbers as input and outputs their sum.

Python

a = int(input())
b = int(input())
print(a + b)

Or, the minimised form:

print(int(input()) + int(input()))
