Question

In this a and “v1” does not come out to be equal…although the content is same..can someone help in suggesting a way such that a comes out to be equal to “v1”

int main()
{
    stringstream s;
    string a;
    char *c="v1";
    s<<c;
    a=s.str();
    cout<<a;
    int i=strcmp(a, "v1");
    cout<<"i="<<i;
}

On comparing a and “v1” do not come out to be equal…please suggest some way such that i may make a to be equal to “v1″…the end goal is to make a to be equal to “v1”.

Answer 1

Because strcmp returns 0 when the inputs match.

(Incidentally, I assume that your actual code is strcmp(a.c_str(), "v1"), because otherwise it wouldn’t have compiled.)
