Array with multiple data types

Question

I want to make array for positions (x, y, z)

It would be something like this:

/*Whatever the type*/ array[100] = {(1, 2, 3), (4, 2, 5)....}

How can I do this?

Array with multiple data types – you can't store multiple data types in a static array, only a single type. Coordinates are usually represented with integers. — Rohan Bari

To be honest, making a struct makes the program much simplified:

struct location {
    int x;
    int y;
    int z;
};

int main(void) {
    location array[100];

    // Example initialization of the first index
    array[0].x = 10;
    array[0].y = 20;
    array[0].z = 30;

    // Or, even better...

    array[0] = {10, 20, 30};
    .
    .
}

In case you want to manually initialize x, y, z of each, then:

location array[100] = {{1, 4, 3}, {3, 0, 2}, {}, ...}

Note: These values are not required, they are just to demonstrate the initialization.

typedef struct ... is useless in C++. struct {...] location; is enough...

Why not follow their required initialization syntax and suggest location array[100] = {{1, 2, 3}, {4, 2, 5} /*...*/ };
