What is a programmer?

A programmer is someone who writes code to instruct computers on how to perform tasks. It’s a bit like giving a computer a set of instructions in a language it understands, so it can run apps, websites, games, or even control hardware.

Programmers use various programming languages to communicate with computers. These languages are designed in a way that allows the computer to "read" and follow the instructions.

C is one of these languages, and it’s well-known for its efficiency and speed, which is why it's been used for so long, especially in system-level programming.

Consider a simple program like this:

#include 

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

This program simply tells the computer to print "Hello, world!" to the screen. The programmer writes the instructions in C, and the computer executes them.
