How to Convert a Single Character to a std::string in C ?

Creating a String from a Single Character

One may encounter the need to convert a single character, represented as a char data type, into a std::string. Acquiring a character from a string is straightforward, simply index the string at the desired location. However, the converse process requires a different approach.

To create a std::string from a single character, several methods are available:

1. Using std::string with an argument count of 1:

<code class="cpp">char c = 34;
std::string s(1, c);
std::cout << s << std::endl;</code>

This method initializes the string with a single character, effectively converting it to a string.

2. Using braced initializer syntax:

<code class="cpp">char c = 34;
std::string s{c};
std::cout << s << std::endl;</code>

Similar to the previous method, the braced initializer syntax automatically constructs a string from the provided character.

3. Using std::string::push_back() method:

<code class="cpp">char c = 34;
std::string s;
s.push_back(c);
std::cout << s << std::endl;</code>

This method creates an empty string and appends the character to it, resulting in a string containing the desired character.
