C ++结构的数组

Question

I have made struct and now I need to create an array for the corresponding struct. Could anyone help me how to go about that? I have looked at stuff online and couldn't really understand it, so could anyone give me an example and explanation on how to create an array of a struct.

 struct CANDIDATE{

    string candiFN;
    string candiLN;
    int partyID;
    int votes;  

};

Answer 1

The same way you make any array. The following makes an array of length 5.

CANDIDATE foo [5];

Then you can fill it however you'd like

for (unsigned int i = 0; i < 5; ++i)
{
    CANDIDATE temp("first", "second", 1, 2);
    foo[i] = temp;
}

Or

for (unsigned int i = 0; i < 5; ++i)
{
    CANDIDATE temp;
    temp.candiFN = "first";
    temp.candiLN = "second";
    temp.partyID = 1;
    temp.votes = 2;
    foo[i] = temp;
}

Note that in C++ using a std::vector introduces more safety and flexibility to most applications.

std::vector<CANDIDATE> bar;
for (unsigned int i = 0; i < 5; ++i)
{
    CANDIDATE temp("first", "second", 1, 2);
    bar.push_back(temp);
}

Answer 2

You can simply do this:

struct CANDIDATE{
    string candiFN;
    string candiLN;
    int partyID;
    int votes;  
}array[5];
//just add an array between } and ; 

Answer 3

You can make an array of values

CANDIDATE foo[5];

or a pointer array

CANDIDATE* foo = new CANDIDATE[5];

The first goes in the stack, the second in the heap and need manual delete

Anyway consider of use std::vector
