Write Your First Code Using C#

C#

Certainly! Here’s a simple “Hello, World!” program written in the C programming language:

#include <stdio.h>

int main() {
printf(“Hello, World!\n”);
return 0;
}

This program includes the standard input/output library (<stdio.h), defines the main function (which is the entry point for the program), and uses printf to print the “Hello, World!” message to the console. The \n is used to create a newline character, so the message is displayed on a new line.

When you compile and run this code, it will print “Hello, World!” to the console.

Hello @Diwakar-S,

This is definitely AI generated content. But why did you post it here and in a different language than the course you seem to be studying for?

If you do use prompts with an AI generative system such as ChatGPT, you need to be specific and say “C#” not just “C” as they have their own syntax, rules, etc.
