How to split input string into char array in c++?

Question

I want to make some kind of algorithm with this

Answer 1

#include <iostream>
#include <string>
using namespace std;

int main()
{
string str = "Hello World";

cout << str << endl;

for(int i = 0; i < str.size(); i++)
{
for(int j = 0; j < (str.size() - 1); j++)
{
if(str[j] > str[j+1])
{
char temp = str[j];
str[j] = str[j+1];
str[j+1] = temp;
}
}
}

cout << str << endl;

return 0;
}

[Edit]: The Dark Lord This is for sorting characters in a string. You don't need to convert the string to char array to sort

Answer 2

That would need an algorithm.

A combo of a

- string to char array

- possibly a to lower function

- then a sorting array that sorts the chars in other.

Answer 3

string mystring = "hello";
char* mychararray = mystring.c_str();

But you probably don't need that. A string can do all the array-like things you need. It has a .size() and you can use mystring[i] to get the i-th character.

To sort a string, you can std::sort(mystring.start(), mystring.end());

Why use an algorithm?

Answer 5

I want to sort the string into alphabetical order

Answer 8

Thank for the respons guys

Answer 9

you can use the extension method for turning a string into a char*:

string a = "abcdefg";
char* b = a.c_str();

now "b" is a char array with the contents of "a".
