Question
Instructions:
- You are strictly not allowed to use anything other than pointers and dynamic memory.
- One function should perform one functionality only.
Task 1
Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task.
- Row wise Sum
- Column wise Sum
- Diagonal wise Sum
Example
data.txt
4
5 1.6 10.2 33.7 99 20.5
3 44 50 96.1
2 8 9
4 74 50 99 19.1
Output:
Sum row wise: 165, 191, 17, 242.1
Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5
Sum diagonal wise: Not Possible
Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.

- Game of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds 50ドル to treasure and no 50ドル turn loss. -$ Subtracts...arrow_forwardIn order to declare a pointer, the ""&"" (ampersand) symbol is used."
