Convert ASCII to string

Question

how to convert ASCII to string I have tried everything but I failed

Answer 1

#include <iostream>
using namespace std;

int main()
{
string str;

for (int i = 0; i < 256; i++)
{
str += static_cast<char>(i);
}

cout << str;

return 0;
}

// now you have an entire ASCII in one string.

Answer 2

Take a look at the codes of the other learners here (not mine). There are some examples.

Answer 3

thanks but what I need is a code which receives input from the user as ASCII numbers and then converts that to a line if string
