 Problem with scanf is that as soon as it encounters space while reading a string it


stops taking input so we either use scanf("%[^\n]%*c", &s) or can use gets function;


#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

int main() 
{
 
    char s[100];
    scanf("%[^\n]%*c", &s);
    // gets(s) another alternative to read string
    
   
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */
    printf ("Hello, World! \n" "%s",s);   
    return 0;
