❮ C++ Keywords

Example

// Create a structure variable called myStructure
struct {
  int myNum;
  string myString;
} myStructure;

// Assign values to members of myStructure
myStructure.myNum = 1;
myStructure.myString = "Hello World!";

// Print members of myStructure
cout << myStructure.myNum << "\n";
cout << myStructure.myString << "\n";

Definition and Usage

The struct keyword defines a structure. Structures are a way to group several related variables into one place.

If a structure has a name it can be used as a data type for any number of variables.

Syntax

struct structName {
  type1 name1;
  type2 name2;
  ...
} varName1, varName2, ...

If a structName is provided, it can be used as a data type for variables which will contain the structure. If the structure does not have a name, it can still be assigned directly to one or more variables (varName1, varName2, ...) declared after the struct.

The struct contains one or more members, each with a data type (type1, type2, ...) and a name (name1, name2, ...).
