Hello, It’s Me

Problem to Solve

In a file called hello.c, in a folder called me, implement a program in C that prompts the user for their name and then says hello to that user. For instance, if the user’s name is Adele, your program should print hello, Adele\n!

Hints
  • Recall that you can get a string from a user with get_string, which is declared in cs50.h.
  • Recall that you can print a string with printf, which is declared in stdio.h.
  • Recall that you can format a string with printf with %s.

Demo

How to Begin

Execute cd by itself in your terminal window. You should find that your terminal window’s prompt resembles the below:

$

Next execute

mkdir me

to make a folder called me in your codespace.

Then execute

cd me

to change directories into that folder. You should now see your terminal prompt as me/ $. You can now execute

code hello.c

to create a file called hello.c in which you can write your code.
