Question

Simulate the flipping of a coin
Print the result of the coin flip : use off numbers for Heads . and even numbers for Tails
Update the number of times the result is Heads
Update the number of times the coin has been flipped

struct coin_prob{
int heads;
int flips;
};
void coin_flip(struct coin_prob * coin);
You may use a rand functioon (assume its already been seeded), but no other pre-defined function

Answer 1

#include<stdio.h>

#include<stdlib.h>

struct coin_prob{

int heads;

int flips;

};

void coin_flip(struct coin_prob * coin)

{

    // generate a random number

    int n = rand();

   

    // even numbers for Tails

    if( n % 2 == 0 )

    {

        printf("Outcome : Tails\n");

       

        // increase the number of flips

        coin->flips++;

    }

    // odd numbers for Heads

    else

    {

        printf("Outcome : Heads\n");

       

        // increase the number of heads

        coin->heads++;

        

        // increase the number of flips

        coin->flips++;

    }

}

int main()

{

    struct coin_prob * coin = (struct coin_prob *)malloc( sizeof(struct coin_prob) );

   

    coin->heads = 0;

    coin->flips = 0;

   

    coin_flip(coin);

    coin_flip(coin);

    coin_flip(coin);

    coin_flip(coin);

    coin_flip(coin);

   

    printf("\nNo of heads : %d\nNo of flips : %d", coin->heads, coin->flips);

   

    return 0;

}
