C++ program to generate random number in circles and find out the sum

In this post, we are going to write a C++ program to generate random numbers in circles and find out the sum

C++ program to generate random numbers in circles and find the sum.

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

int main()
{
int k1 = 0, sum1 = 0, p = 0;
int k2 = 0, sum2 = 0, q = 0;
int k3 = 0, sum3 = 0, r = 1;
int k4 = 0, sum4 = 0, s = 1;
char ch, choice = 'y';

system("cls");
while(choice != 'n')
{
system("cls");

std::cout<<"Press i,l,k & j keys in circles"<<std::endl;
ch = getch();

switch(ch)
{
case 105:
{
if(p==0)
{
k1 = rand()%10;
sum1 = k1+sum1;
std::cout<<"You press up arrow key"<<std::endl;
std::cout<<"The random number = "<<k1<<std::endl;
p++;
q--;
}
else
std::cout<<"Invalid key"<<std::endl;
}
break;

case 108:
{
if(q==0)
{
k2 = rand()%10;
sum2 = k2+sum2;
std::cout<<"You press right arrow key"<<std::endl;
std::cout<<"The random number = "<<k2<<std::endl;
q++;
r--;
}
else
std::cout<<"Invalid key"<<std::endl;
}
break;

case 107:
{
if(r==0)
{
k3=rand()%10;
sum3 = k3+sum3;
std::cout<<"You press down arrow key"<<std::endl;
std::cout<<"The random number = "<<k3<<std::endl;
r++;
s--;
}
else
std::cout<<"Invalid key"<<std::endl;
}
break;

case 106:
{
if(s==0)
{
k4 = rand()%10;
sum4 = k4+sum4;
std::cout<<"You press left arrow key"<<std::endl;
std::cout<<"The random number = "<<k4<<std::endl;
s++;
p--;
}
else
std::cout<<"Invalid key"<<std::endl;
}
break;

default:
std::cout<<"Invalid key"<<std::endl;
}

if(sum1 >= 20)
{
system("cls");
std::cout<<"The up key win"<<std::endl;
getch();
exit(0);
}
if(sum2 >= 20)
{
system("cls");
std::cout<<"The right key win"<<std::endl;
getch();
exit(0);
}
if(sum3 >= 20)
{
system("cls");
std::cout<<"The down key win"<<std::endl;
getch();
exit(0);
}
if(sum4 >= 20)
{
system("cls");
std::cout<<"The right key win"<<std::endl;
getch();
exit(0);
}
std::cout<<"Do you continue (Y/N) = ";
choice = getche();
std::cout<<std::endl;
}
}

```

Output

```Press i,l,k & j keys in circles
You press up arrow key
The random number = 5
Do you continue (Y/N) =

The righ key win
```
