Feel like starting a little series when I post basic C++ code and I disassemble it to easily understand. Enjoy.
The Guessing Game
I will be explaining how this code works. It is a basic number guessing game.
Code:
#include <iostream>
#include <cmath>
#include <cstdlib>
#include <ctime>
using namespace std;
int main()
{
srand(time(0));
int x, y = (rand() % 10) + 1;
do
{
cout << "Guess a number between 1 and 10." << endl;
cin >> x;
if (x == y)
cout << "You are right!" << endl;
else if (x>y)
cout << "Too high! Guess again." << endl;
else if (x<y)
cout << "Too low! Guess again." << endl;
}
while (x!=y)
;system("PAUSE");
return 0;
;}
Now this is a poorly coded game but that isn't the point. Also to note this code will only work on Windows machines because of the system("PAUSE") code. Now time to disassemble the code!
#include <iostream>
#include <cmath>
#include <cstdlib> Get the required libraries.
#include <ctime>
using namespace std; Declare you are using namespace std.
int main() States main is an integer.
{
srand(time(0)); \
int x, y = (rand() % 10) + 1; -> Create a randomly generated number to guess.
do
{
cout << "Guess a number between 1 and 10." << endl; Output the following.
cin >> x; Let the user input a guessing number.
if (x == y) Compare x and y.
cout << "You are right!" << endl; Output the following.
else if (x>y) If x > y do the following.
cout << "Too high! Guess again." << endl; Output the following.
else if (x<y) If x< y do the following.
cout << "Too low! Guess again." << endl; Output the following.
} Closing bracket for do statement.
while (x!=y) While x doesn't equal y pause.
;system("PAUSE"); Pause code.
return 0; Return 0.
;} Closing bracket for do while statement.
Hope you can use this code as a review. Thanks for reading!
