Convert char array to a string in C++

This post will discuss how to convert a char array to a C++ string.

1. Using String Constructor

One way to convert a char array to a string in C++ is to use the string constructor. The string class has several constructors that can create a string object from different types of arguments, such as another string, a character, or an iterator range. One of these constructors can create a string object from a char array or a pointer to an array of characters (such as a C-string).

#include <iostream>

int main()

{

char arr[] = "Techie Delight";

std::string s(arr);

std::cout << s; // Techie Delight

return 0;

}

2. Using `operator=`

Another alternative is to directly assign a char[] to a std::string. This works as operator= is overloaded for std::string, and a C-string would be copied to the string.

#include <iostream>

int main()

{

char arr[] = "Techie Delight";

std::string s = arr;

std::cout << s; // Techie Delight

return 0;

}
