String to char - C++

How can I convert a string to char?

I already Googled and I didn't find the answer to the situation I'm in. Really, I'm trying to convert an int to a char but my compiler doesn't support the to_string function so I decided to convert to from int to string then string to char.

I'm using a char[ ][ ] so I can store integers and chars.

stringstream ss;
ss << j; // j is the integer
string s(ss.str());
ascii_text[1][i] = (char)s;

EDIT:

I'm working with ASCII chars.

This is what I'm trying to do. int a = 10; -> string s = "10"; -> char c = '10';

I'll be happy if I found a way to convert int to char directly.

How can I convert a string to char?

Okay. If you mean char*, then the std::string class has a c_str() method:

std::string myString = "hello";
const char* myStr = myString.c_str();

A char has a size of 1 byte, so you can't fit any string in it, unless that string has a length of 1. You can however get the char at a certain position in a string:

std::string str = "hi bro";
char c = str[0]; // This will be equal to 'h'

You can use the c_str() method to get an array of chars from string.

If I understood you correctly, then all you want to do is get from an integer digit (0-9) to an ascii digit ('0'-'9')? In that case, char(j)+'0' will do.

You should be able to just do 

int j = 3;
char ch;
stringstream ss;
ss << j;
ss >> ch;
