How to convert a char array to a string

Question

Converting a C++ string to a char array is as simple as using the string's c str function and then strcpy.

But how do you do the opposite?I have a char array like this: char arr[] = "This is a test"; which will be transformed to string str = "This is a test."

Answer 1

The string class has a constructor that takes a NULL-terminated C-string:

char arr[ ] = "This is a test";

string str(arr);


//  You can also assign directly to a string.
str = "This is another string";

// or
str = arr;
