Begin8. Two numbers \(a\) and \(b\) are given. Find their arithmetic mean: \((a + b)/2\).

**Solution in Python 3:**

import random

a = random.randrange(1,10)

b = random.randrange(1,10)

print("a = ", a)

print("b = ", b)

print("Arithmetic mean: ", (a+b)/2)

**Solution in C++:**

#include<iostream>

using namespace std;

int main(){

double a,b,c;

cout << "Enter number a: ";

cin >> a;

cout << "Enter number b: ";

cin >> b;

c = (a+b)/2;

cout << "Arithmetic mean: " << c;

return 0;

}
