About Data Structure

Data structures describe the data related to a cluster object and are used as the building blocks of value lists. The data structures follow the following example:
Allocation of a Data Structure
To allocate a data structure on the frame, define the structure variable as follows:

struct MyStructType { int topScore;};
void SomeFunc(void)
{ // Frame allocation 
MyStructType myStruct;
// Use the struct 
myStruct.topScore = 297; 
// Reclaimed when exiting scope }

The memory occupied by the structure is reclaimed when it exits the scope.
To allocate data structures on the heap:
Use new to allocate data structures on the heap and delete to free them, as shown by the following example:

// Heap allocation 
MyStructType*
myStruct = malloc(sizeof(MyStructType));
// Use the structure through the pointer ... 
myStruct->topScore= 297; 
free(myStruct);
