#   # Create Math Game Using C++

I have to create a math game that generates random number

# Project: Math Game In C++

The Math Game is a single-player game. This project is an interesting project. Here, the user can test their calculation skills through this app. If you are able to give the right solution to the problem, then you will get a score of 10 on each question. If not, then the system will end the game. This whole system is in the C++ language.

## Making of the game

This Math game is simply designed in ‘C++’ language. Taking about the features of this system, the user can test their calculation skills through this game. If you are right, then you will get a score of 3. If not, then the system will end the game. The game score is shown at last with a high score. Also, this project is easy to operate and understood by the users.

### Demo ## Code

### Declare Functions

``````#include<iostream>
#include<conio.h>
#include<windows.h>

using namespace std;

void normal();
void medium();
void complex();
void sub(int);
void mult(int);
void div(int);

// main function
int main(){
math();
return 0;
}
``````

### Create Math Function

``````// math function
void math(){
p:
system("cls");
int choice;

cout<<"\n\t<< Math Game >>\n";
cout<<"\n1. Normal";
cout<<"\n2. Medium";
cout<<"\n3. Complex";
cout<<"\n4. Exit";
cin>>choice;

switch(choice){
case 1:
normal();
break;
case 2:
medium();
break;
case 3:
complex();
break;
case 4:
exit(0);
default:
cout<<"\n\tInvalid Opation";
}
getch();
goto p;
}
``````

### Create Modes

``````// normal mode
void normal(){
p:
system("cls");
int choice;

cout<<"\n\tNormal Mode";
cout<<"\n2. Subtraction";
cout<<"\n3. Multiplication";
cout<<"\n4. Division";
cout<<"\n5. Go Back";
cin>>choice;

switch(choice){
case 1:
break;
case 2:
sub(1);
break;
case 3:
mult(1);
break;
case 4:
div(1);
break;
case 5:
math();
break;
default:
cout<<"\n Invalid Opation";
}
getch();
goto p;
}

// Medium mode
void medium(){
p:
system("cls");
int choice;

cout<<"\n\tMedium Mode";
cout<<"\n2. Subtraction";
cout<<"\n3. Multiplication";
cout<<"\n4. Division";
cout<<"\n5. Go Back";
cin>>choice;

switch(choice){
case 1:
break;
case 2:
sub(2);
break;
case 3:
mult(2);
break;
case 4:
div(2);
break;
case 5:
math();
default:
cout<<"\n Invalid Opation";
}
getch();
goto p;
}

// Complex mode
void complex(){
p:
system("cls");
int choice;

cout<<"\n\tComplex Mode";
cout<<"\n2. Subtraction";
cout<<"\n3. Multiplication";
cout<<"\n4. Division";
cout<<"\n5. Go Back";
cin>>choice;

switch(choice){
case 1:
break;
case 2:
sub(3);
break;
case 3:
mult(3);
break;
case 4:
div(3);
break;
case 5:
math();
default:
cout<<"\n Invalid Opation";
}
getch();
goto p;
}
``````
