How to initialize Array of Structure and Access each element with Pointer in C++

Question

In the following program I am having problems with structure initialization. After initialization I need to cout each strcture element using Pointer.

#include <iostream>

using namespace std;

struct student{
int rollno;
float marks;
char name[45];
}*ptr;

int main(){

    //Getting initialization error
student s1[2]={1,50.23,"abc",2,65.54,"def"};

    for(int i=0;i<2;i++){

            //Need to cout using pointers
    cout<<s1[i].rollno<<s1[i].marks<<s1[i].name;
}
return 0;
}

BTW deleted the C tag, because C is quite different in handling this code, particularly, you'd need struct student instead of student, etc. — jpalecek

@jpalecek Good to know that it works but why it isn't it working in eclipse IDE? — sandbox

You should wrap every member of the array in {}:

student s1[2]={{1,50.23,"abc"},{2,65.54,"def"}};

This is unneeded, much more a style issue.

weird. It's work fine for me. (In fact, your original code is work too, but the compiler prints warning for the missing {})
