how to write method definition for the Product* getProductFromID(std::string);

Question

Please tell me how to write definitions for the functions:

Product* getProductFromID(std::string);

void Store:: addMember(Customer* c)

addmember shud add the member details to the vector named cart and i have tried something like this

void Store:: addMember(Customer* c)
{
    Customer c(std::string n, std::string a, bool pm);
    members.push_back(n.str());
}

I get an error saying [Error] 'n' was not declared in this scope.

You declare variables as the parameters for the constructor of your `Customer c`. They should be declared outside, and given an initial value for good measure. — Jonas, Jan 30 '17 at 08:47
@Jonas If you just type MCVE in square brackets, you get a nicely formatted link: [MCVE]. — BoBTFish, Jan 30 '17 at 08:49
@BoBTFish, wow, and I have been formatting it myself as an ordinary link for God knows how long... `[MCVE](link)`... — SingerOfTheFall, Jan 30 '17 at 08:53

This line

Customer c(std::string n, std::string a, bool pm);

declares a function c that takes three parameters and returns a Customer. Not what you want at all.

Assuming that a Customer contains an n member (which really needs a more descriptive name), the function would just look like

void Store:: addMember(Customer* c)
{
    members.push_back(c->n.str());
}
