Get working dir path in C++

In C++, the current working directory can be obtained using the getcwd() function provided by the library.

Here's an example program that shows how to get the current working directory:

``c++ #include #include


int main() {

    char cwd[256];

    if (getcwd(cwd, sizeof(cwd)) != NULL) {

        std::cout << "Current working directory: " << cwd << std::endl;

    } else {

        std::cout << "Error: Unable to get current working directory." << std::endl;

    }

    return 0;

}



In this program, we first declare a character array cwd of size 256 to hold the current working directory. Then, we call the getcwd() function with two parameters: the first is the cwd buffer we defined, and the second is the size of the buffer.
If getcwd() is successful, it returns a pointer to the cwd buffer, and we print it out. Otherwise, we print an error message to the console.

Here's what the output might look like:


Current working directory: /home/user/project

Note that the current working directory can change based on the environment your program is running in, so it's a good practice to check the return value of getcwd()` to make sure it was successful.
