Write a program that defines five integer variables and initializes them to I. 10, 100, 1000, and 10000 and prints them on a single line separated by spaces.

#include <iostream>

using namespace std;

int *my_array;

int array_length;

void FunA(int pos, int input){

my_array[pos] = input;

}

int FunB(){

int n;

cout<<"enter lenth of the array: ";

cin>>n;

my_array = new int[n] ;

return n;

}

int main (){

array_length = FunB();

FunA(array_length-1,20);

delete [] my_array;

return 0; 

}

a) Explain the code snippet above in details.

Please help me determine the C++ code for the following:

The dealer's cost of a car is 85% of the listed price. The dealer would accept any offer that is at least $500 over the dealer's cost. Design an algorithm that prompts the user to input the list price of the car and print the least amount that the dealer would accept for the car.

write a pseudo code for a program which generates even numbers between 1000 and 2000 and then prints them in the standard output.it should also print total sum.

Question No.1 Implement this program by using User-defined functions and Structures.

Write a program that reads students’ names followed by their test scores. The program should output each student’s name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score. Student data should be stored in a struct variable of type studentType, which has four components: studentFName and studentLName of type string, testScore of type int (testScore is between 0 and 100), and grade of type char. Suppose that the class has 20 students. Use an array of 20 components of type studentType. Your program must contain at least the following functions:

1. A function to read the students’ data into the array.

2. A function to assign the relevant grade to each student.

3. A function to find the highest test score.

4. A function to print the names of the students having the highest test score.
