This challenge requires you to print 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.
Example
The required output is:
Hello, World!
Life is beautiful
Program Code
#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%s", s);
return 0;
}
