- Example: Write a C++ program that inputs ten integer values into an array and finds the maximum number in the array. #include using namespace std;vi) In C++, rotate the array given below to left by 2 places and print it in the output. int A[6] = {12, 34, 56, 78, 2, 21}; Expected Output: {56, 78, 2, 21, 12, 34}Declare a vector of integers in C++ named vec and initialize the vector to 10, 20, 30, 40, and 50. Modify the first element of the vector to be 100 and modify the last element to be 1000. The resulting vector should then be 100, 20, 30, 40, and 1000. Using cout statements, display the resulting vector to the terminal.
- C++ A matrix is a rectangular array of numbers that is arranged in a two-dimensional table. Matrices have numerous applications in computer systems. Matrix structures are examined in computer memory, graphics, and cryptography. The Hill cipher, for example, makes use of matrix inversions to encrypt and decrypt data. The intent of this problem is to develop a C++ program that computes and displays the inversion of a 2 x 2 matrix. A matrix is said to have the dimensions m x n if it has m rows and n columns. A square matrix has the same number of rows as columns, and is therefore said to have m x m dimensions. Matrix M shown below is an example of a 2 x 2 matrix. The inverse of a square matrix, M-1, is defined by the equation M(M-1) = I, where I is called the identity matrix. I is a square matrix that is all zeros except for ones along the main diagonal from the upper left corner to the lower right corner. I for a 2 x 2 matrix is: Multiplying a square matrix by its inverse will always…C++ Programming Question 1:Hi, need help with review question 1 if possible.
