In this warm up project, you are asked to write a C++ program proj1.cpp that lets the user or the computer play a guessing game.
The computer randomly picks a number in between 1 and 100, and then for each guess the user or computer makes, the computer informs the user whether the guess was too high or too low. The program should start a new guessing game when the correct number is selected to end this run (see the sample run below).
Check this example and see how to use functions srand(), time() and rand() to generate the random number by computer.
Example of generating and using random numbers:
#include
#include // srand and rand functions
#include // time function
using namespace std;
int main()
{
const int C = 10;
int x;
srand(unsigned(time(NULL))); // set different seeds to make sure each run of this program will generate different random numbers
x = ( rand() % C);
cout << x << endl;
x = ( rand() % C ); // generate a random integer between 0 and C-1
cout << x << endl;
return 0;
}

Here is a sample run of the program:

So far I was able to create the user input ortion of the program, I need help coding the computer generated guessing game,
if the users input choice of computer at the end or choice of play.. if you could help me build on what I have below greatly appreciate it!!! thank you
code I have got so far:
#include
#include
#include
int main(void) {
srand(time(NULL)); // To not have the same numbers over and over again.
while(true) { // Main loop.
// Initialize and allocate.
int number = rand() % 99 + 2; // System number is stored in here.
int guess; // User guess is stored in here.
int tries = 0; // Number of tries is stored here.
char answer; // User answer to question is stored here.
//std::cout << number << "\n"; // Was used for debug...
while(true) { // Get user number loop.
// Get number.
std::cout << "Enter a number between 1 and 100 (" << 20 - tries << " tries left): ";
std::cin >> guess;
std::cin.ignore();
// Check is tries are taken up.
if(tries >= 20) {
break;
}
// Check number.
if(guess > number) {
std::cout << "Too high! Try again.\n";
} else if(guess < number) {
std::cout << "Too low! Try again.\n";
} else {
break;
}
// If not number, increment tries.
tries++;
}
// Check for tries.
if(tries >= 20) {
std::cout << "You ran out of tries!\n\n";
} else {
// Or, user won.
std::cout<<"Congratulations!! " << std::endl;
std::cout<<"You got the right number in " << tries << " tries!\n";
}
while(true) { // Loop to ask user is he/she would like to play again.
// Get user response.
std::cout << "Would you like to play again (Y/N)? ";
std::cin >> answer;
std::cin.ignore();
// Check if proper response.

Answer:
A C++ program was used for a user or the computer play a guessing game.
Explanation:
The C++ code to this question:
#include <iostream>
#include <cstdlib> // srand and rand functions
#include <ctime> // time function
using namespace std;
int main()
{
const int C = 100;// constant integer with defined value 100
char type;// type of option chosen
cout<<"Would you like to (p)lay or watch the (c)omputer play?"<<endl;
cin>>type;// input of type
do{// for first iteration you can't choose q
int x;
srand(unsigned(time(NULL))); // set different seeds to make sure each run of this program will generate different random numbers
x = ( rand() % C);
x++;// random value between 1 and 100
int check=-1;// make initial check=-1
int ends=C;// for type selected as c, make the initial guess to be chosen from 1 to 100
int start=1;
while(1)
{
if(type=='p')// if selected type is p
{
cout<<"Enter your guess in between 1 and 100."<<endl;
cin>>check;
}
else if(type=='c')// if selected type is c
{
check=start+(rand()%(ends-(start-1)));//get a random number between updated start and ends for computer guessing
cout<<"The computer's guess is "<<(check)<<"."<<endl;
}
else// if type is not equal to c or p or q
{
cout<<"Invalid option chosen"<<endl;
break;
}
if(check>x)// if the guess is greater
{
cout<<"Sorry, your guess is too high, try again."<<endl;
ends=check-1;// update ends in case type is c
}
else if(check<x)
{
cout<<"Sorry, your guess is too low, try again."<<endl;
start=check+1;// update start
}
else// if right number is selected
{
cout<<"Congrats, you guessed the correct number, "<<x<<"."<<endl;
break;
}
}
cout<<"Would you like to (p)lay or watch the (c)omputer play or (q)uit?"<<endl;
cin>>type;
}while(type!='q');
return 0;
}
