Help with code

[bb91915]

I am taking a beginners class in C and am attempting to write code for
extra problems my instructor gave us. These are not for grade and are
only used solely for practice. I have a hard time taking pseudocode
and turning it into code. Since I am in a beginners class, we have
only learned so much to date, so what I am presenting will be really
rough, so please pardon my ignorance.

Here are my instructions, with my code to follow:

Using the Borland IDE, design, enter, compile, link, debug, and run a
program called flip.c. Flip.c is a fair coin tossing simulator. You
must use a while loop, a do while loop, a for loop, an array, a
#define, and a user defined function in this program.

Flip.c will do the following 20 times and record the results:
- Use a random number generator to simulate tossing a fair coin 50
times.
- Record the number of heads and tails in two arrays.
- Print the results of the 20 trials in an eye pleasing format

use four #inlcude to include stdio.h, conio.h, time.h, stdlib.h
use #define to create a literal NTOSSES whose value is 50
use #define to create a literal NTRIALS whose value is 20

define int arrays head[NTRIALS] and tail[NTRIALS]

create a prototype for DoTrial(int trial)
create a prototype for PrintTrials()

main()
{
use clrscr() to clear the screen
use randomize() to initialize the random number generator

within a do while loop call the function DoTrial() to toss the coin
NTOSSES times

call PrintTrials() to display the results

return 0

}

void DoTrial(int trial)
{
within a for loop, toss a coin 50 times and record the results in the
trial element of the
head and tail arrays
}

void PrintTrials()
{
within a while use printf to print the head and tails arrays, one
head and one tail per line
}

end of program

************************************************** ************************************************** *****
#include <stdio.h>
#include <conio.h>
#include <time.h>
#include <stdlib.h>

#define NTOSSES 50
#define NTRIALS 20

int head[NTRIALS];
int tail[NTRIALS];

void DoTrial(int trial);
void PrintTrials();

main()

{
clrscr();
randomize();

do
{
void DoTrial(int trial);

} while (NTOSSES < 50);

PrintTrials();
return 0;
}

void DoTrial(int trial)
{

int toss = 0;
for (toss = 0; toss < 50; toss++)
}

void PrintTrials()
{

printf(" Number of Heads Number of Tails");
printf("\t%d\t%d", head[NTRIALS],tails[NTRIALS]);
printf("\n");

Pete,

Thanks, it does exactly what it was supposed to do, however, we are not
at this level yet in class, but I will dissect it so that I know what
every line of code is doing.

Thanks again,

Bryon

I hope it's not too difficult.
If you have further questions, feel free to ask.
