Struct

A struct is a variable that can hold multiple values. Individual values are accessed using the dot (".") operator.

The convenience of using a struct is that it can be easily copied using assignment operators, and makes for cleaner code than multiple enumerated (or unrelated) variables.

These are C-style structs, so you can't have member functions.

// the struct declaration
struct MyStruct
{
     // list of variables in the struct
     int a;
     float b;
};

// function declaration using a struct
void myFunction(struct MyStruct strStruct);

void main()
{
     // declare a couple of local variables based on the struct
     struct MyStruct strStruct1, strStruct2;
     // Access the components of the struct with '.'
     strStruct1.a = 5;
     strStruct1.b = 3.4;
     strStruct2.a = 7 - strStruct1.a;
     strStruct2.b = 8.5 - strStruct2.b;
     // Or use the struct as a whole
     strStruct1 = strStruct2;
     myFunction(strStruct1);
}

// function implementation using a struct
void myFunction(struct MyStruct strStruct)
{
     int x = strStruct.a;
     return;
}
