    file i/o problems

    i cant figure out how to fix this!!!

    Code:
    #include <iostream>
    #include <fstream>
    
    using namespace std;
    
    int main()
    {
        ofstream legs;
        legs.open("legs.txt");
        legs<<"legs,legs,legs"<<endl;
        legs.close();
        system("pause");
        ifstream legs("legs.txt")
        return 0;
    };
    its suppose to make a file called legs and make the text in the file legs,legs,legs and then its suppose to open the previously created legs file!! but it doesnt

    you have declared legs to be an ofstream and then you redeclare it to be an ifstream.
    use a different variable name.

    Something like this ?
    Code:
    int main() {
        ofstream legs;
        legs.open("legs.txt");
        legs<<"legs,legs,legs"<<endl;
        legs.close();
        
        ifstream ilegs("legs.txt");
        string s;
        ilegs >> s;
        cout << s << endl;
        return 0;
    };
