Okay, you sure are asking alot, I'll help with a litte.
Something like that for dynamic memory allocation, you just have empty functions, give it a try!Code:// Dynamically allocating memory private: char *pointer; // Pointer to string ... // Constructor MyInt(char Int_String[], int size) { int i = 0; pointer = new int[size]; pointer = Int_String; while(Int_String[i] != 0) { if(isDigit(Int_String[i])) { *pointer = "0"; break; } } }
