array of structure problems

Hi all,

Im trying to make an array of structures

Code:

---

struct infoAttr{
        char Name[20];
        int age
};


infoAttr p1 = {"mike", 20};
infoAttr p2 = {"Dave",23};
infoAttr p3 = {"Alex", 23};

infoAttr people[3] = {p1,p2,p3};

---

Im getting an error with the last line saying:

"error C2440: 'initializing' : cannot convert from 'struct infoAttr' to 'char'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called"

Its probably really simple but its got me stumped.

Thanks

Why not just do

Code:

---

infoAttr people[3] = {
  {"mike", 20},
  {"Dave",23},
  {"Alex", 23},
}

---

What Salem said, although Mike is 22, and I would advise using std::string instead of char arrays. Just much easier, IMO. You may want to overload an = operator or something if you want to directly assign one struct to another.

Thanks for the replies. I've been using your example now for a few days, but unfortunately I now need to expand on it.

Lets say my structure is used to store information of every house hold in a road so its like this:

Code:

---


struct infoAttr{
        char Name[20];
        int houseNumber;
};

infoAttr road1[3] = {
  {"mike", 20},
  {"Dave",23},
  {"Alex", 22}
};

infoAttr road2[3] = {
  {"Rich", 27},
  {"Steve",13},
  {"Andy", 29}
};

---

I want to combine the above array's into a 2d array called all roads like so

Code:

---

infoAttr allRoads[2][3] = {road1,road2};

---

However im getting the error message

Code:

---

error C2440: 'initializing' : cannot convert from 'struct infoAttr [3]' to 'char'
        This conversion requires a reinterpret_cast, a C-style cast or function-style cast

---

Any ideas? Thanks :-)

Sorry I didnt make myself clear. The problem im having isnt with the line allRoads[0][1], thats just showing what im attempting to do. The problem im having is with the line above it, the infoAttr allRoads[2][3] = {road1,road2};

I'll remove the allRoads[0][1] bit from the above code as that makes it confusing :-)

So the following line gives the error:

Code:

---

infoAttr allRoads[2][3] = {road1,road2};

---

gives error:

Code:

---

error C2440: 'initializing' : cannot convert from 'struct infoAttr [3]' to 'char'
        This conversion requires a reinterpret_cast, a C-style cast or function-style cast

> infoAttr allRoads[2][3] = {road1,road2};
You can't assign arrays.

You could point at them though, with
infoAttr *allRoads[2] = {road1,road2};
