Project 2 - Greeter 💬

For our second project, lets make a program that greets the user.

It should ask the user for their first name and then print a response!

Ex.

> What is your first name?
> Joe
> Hello Joe, nice to meet you!

For this project, let’s assume the maximum length of someone’s first name is 63 characters.

Tasks 🎯

Print the question.

Hint ❓

You can print something by writing printf("the stuff I want to print");. If this seems unfamiliar to you, then check out the hello_wordprintf section.

Don’t forget the \n at the end of the printf statement in order to let the scanf to detect user input on the next line!

Solution ✅

#include <stdio.h>

int main() {
    printf("What is your name?\n");

    return 0;
}

Get user input for their first name.
