default values for struct members (noob q)

how do you intialize struct members?

A struct can have constructors and functions associated with it just like a class can. Just make a constructor for the struct that assigns default values to the struct's data members. Is this what you mean or are you talking about something else?

Code:

---

#include <iostream>

struct mystruct
{
    int iVal;
    float fVal;
    mystruct() : iVal(5), fVal(9.9f) {}
};

int main()
{
    mystruct item;

    std::cout << item.iVal << ' ' << item.fVal << std::endl;

    return 0;
}

---

Should output: 5 9.9

that is excactly what I wanted to know. Thank you.

The alternative is an initialization list upon variable creation:

Code:

---

#include <iostream>

struct mystruct {
  int  iVal;
  float fVal;
};

int main()
{
  mystruct item = { 5, 9.9 };
 
  std::cout<< item.iVal <<' '<< item.fVal <<std::endl;
}
