### Coin Toss

I've approached a very annoying problem with my code.
The idea behind my assignment is that it'll toss a coin 100 times, 1 = heads, 2 = tails, and count how many heads and tails there are in a million tosses, while calculating the percentage.

 ``12345678910111213141516171819202122232425262728293031`` `````` #include using namespace std; int main() { for (int x = 0; x < 1000000; x++) { srand(time(NULL)); int y = rand()%2+1; int z=0, g=0; while (y=2) { z++; } while (y=1) { g++; } } float perch = (g/1000000)*100; float perct = (z/1000000)*100; cout << "Number of heads = " << g << ", percent = " << perch << "%" << endl; cout << "Number of tails = " << z << ", percent = " << perct << "%" << endl; system("pause"); return 0; }``````

The problem is after debugging, I'm not receiving anything--all I have on the output is a blank.
you are assigning values to y.(by doing y=2 and y=1).you need to check like this: y==2
you also need g and z to be of float types or the percentage would be calculated as zero(cause they are int)

#include<ctime>
#include<iostream>
#include<cstdlib>
#include<conio.h>

using namespace std;

int main()
{

float z=0, g=0;
int y;

srand(static_cast<unsigned int>(time(0)));
for (int x = 0; x < 1000000; x++)
{

y = (rand()%2)+1;
if(y==2)
{

z++;
}

if(y==1)
{

g++;
}

}
double perch = (g/1000000)*100;
double perct = (z/1000000)*100;
cout << "Number of heads = " << g << ", percent = " << perch << "%" << endl;
cout << "Number of tails = " << z << ", percent = " << perct << "%" << endl;

getch();
}

You have infinite loop on lines 10 and 16. Change loop statement to conditional statement.
