Question

Write a program that simulates the toss of a coin. Whenever a coin is tossed the result will be either a head or tail. Prompt the user as shown by entering an ‘H’ for heads or ‘T’ for tails. Use a loop for input validation of an ‘h’ or ‘t’. Make sure that both an upper case and lower case will be accepted. Have the computer generate a random number. Assign a char variable a (‘h’ ^ ’t’) head or tail so that the probability of either is equally possible. Display the outcome of the coin toss as text, either “You Win!” or “Computer Wins” as a result of the user’s guess compared to the random (‘h’ ^ ‘t’) generated. Use a loop for multiple flips of the coin. The user enters either ‘Y’ or ‘y’ to continue the program.   Keep track of the number of wins and losses. Display the summary when the user decides to quits the program. Example of the output is shown below:

Answer 1

Program:

#include<stdio.h>
#include <stdlib.h>

//main function
int main()
{
int n, m = 0, p = 0;
char ch, yn;
do
{
//generate random number 0 or 1
int n = rand()%2;
//prompt user to enter head or tail
printf("Enter \'H\' for for heads or \'T\' for tails: ");
scanf(" %c", &ch);
//check who is won
if(n==0 && (ch=='h'||ch=='H') || n==1 && (ch=='t'||ch=='T')){
printf("You Win!\n");
p++;
}
else
printf("Computer Wins!\n");

m++;
//prompt user for continuation
printf("Are you want to continue? (y/n): ");
scanf(" %c", &yn);
}while(yn=='y' || yn=='Y');

//display summary
printf("Summary: ");
printf("Total number of tosses : %d\n", m);
printf("You win %d number of times\n", p);
printf("Computer wins %d number of times\n", m-p);
}

Output:
