Hello World! in C

---

Objective

---

In this challenge, we will learn some basic concepts of C that will get you started with the language. You will need to use the same syntax to read input and write output in many C challenges. As you work through these problems, review the code stubs to learn about reading from stdin and writing to stdout.

---

Task

---

This challenge requires you to print Hello, World! on a single line, and then print the already provided input string to stdout. If you are not familiar with C, you may want to read about the printf() command.

---

Solution:

#include <stdio.h> #include <string.h> #include <math.h> #include <stdlib.h> int main()  {          char s[100];     scanf("%[^\n]%*c", &s);     printf("Hello, World!\n");      printf("%s", s);     return 0; }
