write this program in c++ please and show me an example of output if possible:

1. Given x, y, z. Calculate a, b if:

2. Given real positive numbers a, b, c, x, y. Determine whether a brick with edges a, b, c will pass into a rectangular hole with sides x and y. To push the brick is allowed only so that each of its edges is parallel or perpendicular to each of the sides of the hole.

3. Given a natural number. Assign to it the same number on the left. 34 => 3434

4. Find the number of even numbers in the whole number entered from the keyboard.

5. Given a real number a and a positive integer n. Calculate a (a + 1) ... (a + n-1).

6. Calculate the infinite sum with a given accuracy (> 0). We assume that the required accuracy is attained if the sum of the first few terms is calculated and the next summand is less modulo than , and all subsequent terms can no longer be taken into account. Specified infinite sum:
