C++ Programming Exam

Tasks 1 and 2 are done on paper and a scan or photo is attached. After attaching tasks 1 and 2, we start solving the remaining tasks. Each task is saved in a separate file.

Task 1.

Discuss two types of loops in C++. Provide an example of program code using one of them.

Task 2.

Describe the operation of the following function:

double functionnowa(double a, double b, unsigned n)
{
  double variable1;
  if(b==1)
  return n*a;
  else
  {
    variable1=a*(1-pow(b,n))/(1-b);
    return variable1;
  }
}

What value will it return when we call it with arguments (2,3,4).

Task 3.

Write a program code that calculates the arithmetic mean of two integers provided by the user.

Task 4.

The user provides three real numbers a, b, c, which are the lengths of the sides of a triangle. Write a program that checks whether this triangle is right-angled.

Task 5.

The user enters a natural number n that is a dimension of the R^n space, and then two vectors in this space. Write the program code that will save these vectors in arrays and calculate their scalar product.

Task 6.

Write the program code that will print all the divisors of the natural number entered by the user.
