C++ Simulating Coin Toss (C++ Functions and Loops) - Write a function named coinToss that simulates the tossing of a coin. When you call the function, it should generate a random number in the range of 1 through 2. If the random number is 1, the function should display "heads", if it is 2, it should display "tails". Demonstrate the function in a program that asks the user how many times the coin should be tossed, and then simulates the tossing of the coin that number of times.

C++ Homework Solution

#include
#include // for rand() and srand()
#include // for time()

using namespace std;

// function to simulate a coin toss
void coinToss() {
    int num = rand() % 2 + 1; // generate random number 1 or 2
    if (num == 1) {
        cout << "heads" << endl;
    } else {
        cout << "tails" << endl;
    }
}

int main() {
    srand(time(0)); // seed the random number generator with the current time

    int numTosses;
    cout << "How many times do you want to toss the coin? ";
    cin >> numTosses;

    for (int i = 0; i < numTosses; i++) {
        cout << "Toss " << i+1 << ": ";
        coinToss();
    }

    return 0;
}
The coinToss() function uses rand() to generate a random number in the range of 1 through 2, and then displays "heads" if the number is 1 and "tails" if the number is 2. In the main() function, the user is prompted for how many times they want to toss the coin, and then a loop calls the coinToss() function that number of times.
