Is that right ??

Question

Given a string S containing a number of substrings separated by spaces. Write a program to do the following:
1. Count the number of substrings in S and print S with extra spaces deleted.
2. Define a dynamic array of pointers (a pointer for each substring in S).
3. Save a pointer to each substring S into the array.
Hint: use strtok function.

#include <iostream>
#include <bits/stdc++.h>
#include <cstring>
using namespace std;

int main() {
char s[] = " Hello friends Welcome to my house ";
char delim[] = " ";
cout << s << endl;
char *token = strtok(s,delim);
int count = 0;
cout << "Will be --> ";
// To remove spaces
// And we used the pointer to point at the substrings
// And to count the substrings
vector<char *> arr;
while(token) {
count++;
arr.push_back(token);
cout << token << " " ;
token = strtok(NULL,delim) ;
}

cout<< endl <<" Number of substrings: " << count << endl;

return 0;
}
