( Please Help Urgently ) Can anyone show me a different way of writing this code in C++, Thanks

#include  #include  using namespace std; const int SIZE = 100; const int MAX_WORD = 9999, MIN_WORD = -9999; const long SENTITEL = -99999; enum Commands { READ = 10,WRITE , LOAD = 20, STORE, ADD = 30, SUBTRACT , DIVIDE , MULTIPLY, BRANCH = 40, BRANCHNEG, BRANCHZERO, HALT }; void load(int * const); void execute(int * const, int * const, int * const, int * const, int * const, int * const); void dump(const int *const, int, int, int, int, int); bool validWord(int); int main() { int memory[SIZE] = { 0 }; int accumulator = 0, instuctionCounter = 0, instructionRegister = 0, opCode = 0, operand = 0; load(memory); execute(memory, &accumulator,&instuctionCounter,&instructionRegister,&opCode,&operand); dump(memory, accumulator, instuctionCounter, instructionRegister, opCode, operand); system("pause"); //cin.get(); return 0; } void load(int *const loadMemory) { long instruction; int i = 0; cout << "*** Welcome to Simpletron *** " << "*** Please Enter your Program one instrution *** " << "*** (or Data word) at a time.
