Please explain the answers and how they were gotten step by step. The programming language is C + +. ### Problem 26Consider the following C++ program.```cppvoid a(int &x, int y) { x = y; y = x + 1;}int b(int &x, int y) { y = x + 1; x = y; return y;}void c(int x[], int y) { if (y < 1) return; cout << x[y - 1] - y; c(x, y - 1);}int main() { int x[6] = {1, 2, 3, 4, 5, 6}; int y[3] = {5, 4, 3}; cout << y[x[1]] << x[y[1]] << endl; // line (a) a(x[0], x[1]); cout << x[0] << x[1] << endl; // line (b) cout << b(2), x[3] << endl; // line (c) cout << x[2] << x[3] << endl; // line (d) c(y, 3); cout << endl; // line (e)}```#### (a) What is the output at line (a)?**Answer:** 3#### (b) What is the output at line (b)?**Answer:** 22#### (c) What is the output at line (c)?**Answer:** 4#### (d) What is the output at line (d)?**Answer:** 44#### (e) What is the output at line (e)?**Answer:** 024 ### Explanation:- **Line (a)**: `cout << y[x[1]] << x[y[1]] << endl;` - `x[1]` is 2, so `y[x[1]]` is `y[2]` which is 3. - `y[1]` is 4, so `x[y[1]]` is `x[4]` which is 5. - Therefore the output is `3`.- **Line (b)**: `a(x[0], x[1]);` - `x[0]` becomes equal to `x[1]` which

Given C++ program is,void a(int &x, int y) { x = y; y = x + 1;}int b(int &x, int y){…

Answer: 22 (b) What is the ouput at line (b)? Answer: int x [6] = {1, 2, 3, 4, 5, 6}; int y [3] = {5, 4, 3}; cout << y[x [1]] % x[y[1]] << endl; a(x [0], x[1]); 4 cout << x[0] << x[1] << endl; cout <

C PROGRAM Reverse + Random Formula In the code editor, there's already an initial code that contains the function declaration of the function, computeReverseNumber(int n) and an empty main() function. For this problem, you are task to implement the computeReverseNumber function. This function will take in an integer n as its parameter. This will get the reverse of the passed integer and will then compute and return the value: result = (original_number + reverse_of_the_number) / 3 In the main() function, ask the user to input the value of n, call the function computeReverseNumber and pass the inputted value of n, and print the result in the main() with two (2) decimal places. SAMPLE: Input n: 20 Output: 7.33 Input n: 123 Output: 148.00
c++ coding language I need help with part B and C please. If you are unable to do both, then PLEASE prioritize part C. I am really stuck and really can use the help. This is the code for c that was provided in order to guide me: const int N =31; // N parking spaces bool parking[N]; // the garage void EmptyTheLot(bool parking[], int N) { for(int i=0; i<N; i++) p[i]=false; // empty space } // returns -1 if no space found, //otherwise it returns 0<=i<N for a valid space. int FindSpace(int PlateNumber, bool parking[], int N) { // ????? } main() { EmptyTheLot(parking, N); // start with an empty parking garage. // get plate numbers and fill lot. }
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, Arrays Lights The park is illuminated by n (1 < n < 100) lights. Each of them shines all night or not. Of course, which lights were on the first night and which were not. Every other night the condition of the lamps shall be determined by the following rules: the lamp will not illuminate if both of its neighbors were lit last night; the lamp shall illuminate if one of its neighbors was illuminated last night and the other was not; if neither of the first two rules applies to the lamp, it will illuminate when the night is even and will not illuminate when the night is odd. Create a program to determine which lights are on and which will not be lit when k (1 < k < 100) nights have elapsed, and to find which night the most lights were lit and which the least. If there are several identical nights with the most or least lights lit, the night with the lower number must be indicated. The first line of the original data file contains two integers: the number of…

#Solve it with C programing Mr. X is a student of Computer Science. He is facing a problem and needs your help to solve it.The problem is, you will be given N integer numbers( 4<n<=100) which are arranged side by side (x1,x2,x3,x4,.....).Now you have to sort those items in ascending order. After doing this , your job is to print the items in a sorted way and find the median.[NB: when N is odd , Median= (N+1)/2; When N is even Median= (N/2)+1 ] Sample Input: 74 7 11 2 9 3 5Sample Output:2 3 4 5 7 9 115
