Section 3 - Memory Management

	OS Allocates four areas of memory on program startup
		Code Segment
			Program Instructions
			Address of functions
		Data Segment
			Global Memory
				Global Variables
				Static Variables
				Literals
					Notation for representing fixed value. (ints, chars etc.)

		Function Call Stack
            Purpose
                Manages the order of the function calls, and stores local variables
			Local Data
		Heap (Part of Data Segment)
			Dynamically allocated memory

void push(eIOfseoifj, esofihesofhies){
  
  if( data->size + 1 > data->capacity){
      ElementType **temp = data -> elements
      
      data->elements = (ElementType **) malloc (2* data->capacity * sizeof(ElementType *))
      int i;
      for(i = 0 ; i < size ; i++){
          data->elements[i] = temp[i]
    }
  
  data->elements[data->size++] = element;

}

  malloc(sizeofBlockType)

  calloc(1, sizeof(BlockType))
