Lab 2.1 structWrite a complete program with a struct to hold the data for one unit (container or pallet). Load the pertinent data and then output it to the screen. Use the following functions:main * Uses new to obtain space for the data structure * Calls the other two functions * Deletes the space obtained using new

input * Reads all the data from the user * Puts all this data into the structure

output * Prints the data in a neat formatPut the main function first. Use the function names and specified above. Arrange the functions in the order listed above. Use the following data and field names:

uld - Pallet

abbreviation - PMC

uldid - PMC46890IB

aircraft - 737

weight - 1289

destination – BFL

cPtr = nullptr;
return 0;

}
void input(Cargo* cPtr)

cout << "input called\n";
cout << "Please input Container or Pallet: ";
getline(cin, cPtr->loadType); ///eliminates (*cPtr).loadType

}
void output(Cargo *cPtr)
{ cout << "output called\n";
cout << cPtr->loadType << endl;

Please help me with the following coding

3. bob is arguing that if you use output feedback (ofb) mode twice in a row to encrypt a long message, m, using the same key each time, it will be more secure. explain why bob is wrong, no matter what encryption algorithm he is using for block encryption (15 points).

We as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). in a computer’s language, however, it is preferred to have the operators on the right side of the operands, i.e. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix.write a program that takes an “infix” expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % (example infix expression: (7 - 3) / (2 + 2)postfix expression: 7 3 - 2 2 + /result: 1guidelines: 1. you will need to use stacks in three placesa. one for the parenthesis check [char stack]b. one during infix to postfix [char stack]c. one during evaluation [int stack]for a and b above, you can use same array and same push, pop method as both ofthem are char. but for evaluation you have int stack and you might consider to createanother push pop method to handle it. maybe push_int, pop_int, etc. or find otherstrategy to utilize existing push pop method2. you can create a function for obtaining operator priority. that function should take anoperator as input and return its priority as an integer. this function will you a lot andreduce repeated code3. during evaluation you will need to convert char into integer. example for single digit: char c = '5'; int x = c - '0';

1. you have a small business that is divided into 3 departments: accounting, sales, and administration. these departments have the following number of devices (computers, printers, etc.): accounting-31, sales-28, and administration-13. using a class c private network, subnet the network so that each department will have their own subnet. you must show/explain how you arrived at your conclusion and also show the following: all available device addresses for each department, the broadcast address for each department, and the network address for each department. also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).
