Answer Posted / sanish joseph

both malloc and new functions are used for dynamic memory
allocations and the basic difference is: malloc requires a
special "typecasting" when it allocates memory for eg. if
the pointer used is the char pointer then after the
processor allocates memory then this allocated memory needs
to be typecasted to char pointer i.e (char*).but new does
not requires any typecasting. Also, free is the keyword used
to free the memory while using malloc and delete the keyword
to free memory while using new, otherwise this will lead the
memory leak.

#include #include #include #include void insert(char *items, int count); int main(void) { char s[255]; printf("Enter a string:"); gets(s); insert(s, strlen(s)); printf("The sorted string is: %s.\n", s); getch(); return 0; } void insert(char *items, int count) { register int a, b; char t; for(a=1; a < count; ++a) { t = items[a]; for(b=a-1; (b >= 0) && (t < items[b]); b--) items[b+1] = items[b]; items[b+1] = t; } } design an algorithm for Insertion Sort

Objective The objective of this problem is to test the understanding of Object-Oriented Programming (OOP) concepts, in particular, on encapsulation. Problem Description Create a program for managing customer’s bank accounts. A bank customer can do the following operations: 1. Create a new bank account with an initial balance. 2. Deposit money into his/her account. 3. Withdraw money from his/her account. For this operation, you need to output “Transaction successful” if the intended amount of money can be withdrawn, otherwise output “Transaction unsuccessful” and no money will be withdrawn from his/her account. Input The input contains several operations and is terminated by “0”. The operations will be “Create name amount”, “Deposit name amount”, or “Withdraw name amount”, where name is the customer’s name and amount is an integer indicating the amount of money. There will be at most 100 bank accounts and they are all created on the first month when the bank is opening. You may assume that all account holders have unique names and the names consist of only a single word. Output The output contains the transaction result of withdrawal operations and the final balance of all customers after some withdrawal and deposit operations (same order as the input). Sample Input Create Billy 2500 Create Charlie 1000 Create John 100 Withdraw Charlie 500 Deposit John 899 Withdraw Charlie 1000 0
