Write a program that prompts the user for a sentence (again, pick a maximum length), and prints each word on its own line.

#define __STDC_WANT_LIB_EXT1__ 1 // Active C11 extended functions (this case is gets_s)
#include<stdio.h>

int slen(const char *); // I don't want to include whole string lib just for get size

int main(void) {
  char s[500];
  printf("%s","Enter a sentence: ");
  if(!gets_s(s,500)) {
    puts("Error!");
    getchar();
    return 0;
  }
  for(int i=0;i<slen(s);i++)
    if(s[i]!=32)
      putchar(s[i]);
    else
      putchar(10);
  putchar(10);
  getchar();
  return 0;
}

int slen(const char *s) {
  int i;
  for(i=0;s[i]!=0;i++);
  return i;
}
