Split string into array of chars in C++

Question

Hello, I'm writing a program that requires a string to be inputed, then broken up into individual letters. Essentially, I need help finding a way to turn "string" into ["s","t","r","i","n","g"]. The strings are also stored using the string data type instead of just an array of chars be default. I would like to keep it that way and avoid char, but will use it if necessary.

Any help would be nice, thank you in advance.

Answer 1

string a = "hello"; 
cout << a[1];

I hope that explains it

Answer 2

A string is just a sequence of the underlying character (i.e. char for std::string and wchar_t for std::wstring).

Because of that, you easily get each letter:

for (std::string::size_type l = 0; l < str.length(); ++l)
{
    std::string::value_type c = str[l];
}

Answer 3

Assuming you already have the string inputted:

string s("string");
vector<char> v(s.begin(), s.end());

This will fill the vector v with the characters from a string.

Answer 4

Try using the c_str() method of std::string:

#include <string>
using namespace std;

int main(void)
{
  string text = "hello";
  size_t length = text.length() + sizeof('\0');
  char * letters = new char[length];
  strcpy(letters, length.c_str());
  for (unsigned int i = 0; i < length; ++i)
  {
      cout << '[' << i << "] == '" << letters[i] << "'\n";
  }
  return EXIT_SUCCESS;
}
