I want to open a file with notepad in C++ but how?

I am trying to open a text file by getting user input.

system(topicName.c_str());

is not working where topicName is the user input.

Even as a user I am inputting the right name of the file it is not opening with the corresponding file (.txt)

 cout << "Intro To C " <<endl; 
 cout << "Intro To C++" <<endl; 
 cout << "Intro To Java " <<endl; 

 cout << "\t\tWhich Topic You Want to edit: ";
 cin.ignore(1000, '\n');
 getline(cin, topicName);

 system(topicName.c_str());

Suppose you have the following files in the directory in which you are running the program:

File List

Then, the following code will serve your job:

#include <iostream>
#include <stdlib.h>

using namespace std;

int main() {
    cout << "Intro To C" << endl;
    cout << "Intro To C++" << endl;
    cout << "Intro To Java" << endl;

    string topicName;

    cout << "\t\tWhich Topic You Want to edit: ";
    getline(cin, topicName);

    topicName = "notepad \"" + topicName + "\"";

    system(topicName.c_str());
    return 0;
}

Then upon running, we get the following output:

Intro To C
Intro To C++
Intro To Java
        Which Topic You Want to edit: Intro To Java

Upon typing this, the file will be opened in notepad if you are running it in a Windows system. Please change your program accordingly if you are using a different operating system.
