Problems with a simple coin flipping program
Hi,
Although I have had a few years of experience with C programming, I still consider myself a fairly new user. This is because my debugging skills are primitive and I still can't seem to get around simple errors.
I was writing a code to:
- flip a coin a 1000 times
- display "heads" or "tails" as each flip comes up
- count the result of each flip, and display percentages of heads and tails when its done
Although I initially wrote another code which worked fine, I decided to simplify the code. However, I get a few errors, which I cannot seem to get around.
Code:
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#define FLIPS 1000
int main()
{
int flips, result;
int head_count = 0;
float hpercent, tpercent;
srand((unsigned)time(NULL));
for(flips=0; flips<FLIPS; flips++)
{
result = rand() % 2;
if(result)
{
head_count += 1;
printf("Heads ");
}
else
printf("Tails ");
}
}
hpercent = ((float)head_count / FLIPS) * 100; /* The errors start here */
tpercent = 100.0 - hpercent;
printf("Heads: %.2f percent \n", hpercent);
printf("Tails: %.2f percent \n", tpercent); /* And end here */
return(0);
}
These are the error messages:
coinflip2.c:32: 'head_count' undeclared here <not in a function>
coinflip2.c:32: initializer element is not a constant
coinflip2.c:32: warning: data definition has no type or storage class

coinflip2.c:35: warning: data definition has no type or storage class
coinflip2.c:36: parse error before string constant

If anybody has any suggestions, please feel free to help me out.
