Group B Q1) A vector is given by x = [-3.5-5 6.2 11 0 8.1-903-132.5]. Using conditional statements and loops, write a program that creates two vectors from x-one (call it P) that contains the positive elements of x, and a second (call it N) that contains the negative elements of x. In both P and N, the elements are in the same order as in x.

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 to treasure and no $50 turn loss. -$ Subtracts…

C++ Coding: Arrays Implement a 4x4 two-dimensional array of integers. Use a nested loop to populate the array with values 20 to 35 inclusive. Use a nested loop to output the array as a grid. Use a single loop to output all elements in the second row. Use a single loop to output all elements in the third column. Use a single loop to output all elements in the first diagonal (r==c). Use a single loop to output all elements in the opposing diagonal. Example Output: 20 21 22 2324 25 26 2728 29 30 3132 33 34 35Row 2: 24 25 26 27Col 3: 22 26 30 34Diagonal 1: 20 25 30 35Diagonal 2: 23 26 29 32
