2- std::string::append()

This method is just similar as += operator discussed above but It gives us another advantage. By using this method we can append as many characters we want.

// appends n copy of character x at end of string
string s(size_t n, char x);

C++

// CPP program to get a string from single
// character.
#include<bits/stdc++.h>
using namespace std;
 
 
int main() {
  string str;
  str.append(1, 'G');
  cout << str << endl;
}

How to convert a single character to string in C++?

How to convert a single character to a string object.
Examples:

Input :  x = 'a'
Output : string s = "a"

Input :  x = 'b'
Output : string s = "b"

The idea is to use string class which has a constructor that allows us to specify size of
string as first parameter and character to be filled in given size as second parameter.

This is called Class-fill constructor.

// Create a string of size n and fill
// the string with character x.
string s(size_t n, char x);

NOTE- size_t is typedef of unsigned long long hence we should not pass negative parameters.

CPP

// CPP program to get a string from single
// character.
#include<bits/stdc++.h>
using namespace std;
 
string getString(char x)
{
    // string class has a constructor
    // that allows us to specify size of
    // string as first parameter and character
    // to be filled in given size as second
    // parameter.
    string s(1, x);
 
    return s;   
}
 
int main() {
  cout << getString('a');
  return 0;
}

Output

However there are many other ways by which you can convert character into string. The method mentioned above only works while initialization of string instance.
