If I understood correctly your question you are asking how to use getline with some member variable of a struct.

Look at this and you should figure out with ease how to finish:

C++ Syntax (Toggle Plain Text)

std::string nonMemberString;
nonMemberString = "Some text";
std::cout << std::endl << nonMemberString << std::endl;
std::cout << "Insert some other text" << std::endl;
getline(cin, nonMemberString);

std::string nonMemberString; nonMemberString = "Some text"; std::cout << std::endl << nonMemberString << std::endl; std::cout << "Insert some other text" << std::endl; getline(cin, nonMemberString);

this will store the hard coded string "Some text" into the non member string nonMemberString and print it out, and then will get user input with getline.

On the other hand, we have

C++ Syntax (Toggle Plain Text)

struct example {
     std::string memberString
     someType otherStuff;
};
 
int main(void) {
     example myExample;
     myExample.memberString = "Some text";
     std::cout << std::endl << myExample.memberString << std::endl;
     std::cout << "Insert some other text" << std::endl;
     // ... now it should be evident how to use getline
     return 0;
}

struct example { std::string memberString someType otherStuff; }; int main(void) { example myExample; myExample.memberString = "Some text"; std::cout << std::endl << myExample.memberString << std::endl; std::cout << "Insert some other text" << std::endl; // ... now it should be evident how to use getline return 0; }

Compare the two and you will sort things out in a blink.

Help how can you sort
