Structures

GeeksForGeeks - Structures in C++

A struct is more or less a grouping of variables, and is defined like:

// -------- Option 1 ----------
struct Point {
   int x, y;
} p1;  // The variable p1 is declared with 'Point'
// -------- Option 2 ----------
// Delared without initializing a variable to it.
struct Point {
   int x;
   int y;
};

int main() {
    // You can initialize a variable after the struct definition.
    struct Point p1;
}
