Coin Toss program not working Visual Studio 2010

A book exercise prompts me to create a program that simulates coin tossing. My friend says he ran my code in a native GNU compiler, and it worked, but I'm receiving the following errors when I try to run it in Visual Studio 2010:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int result;
int flip();
int main(void)
{
srand(time(NULL));
int heads = 0;
int tails = 0;
unsigned counter;
for(counter = 1; counter <= 100; counter++)
{
result = flip();
if(result == 1)
{
printf("Heads\n");
heads++;
}
else
{
printf("Tails\n");
tails++;
}
}
printf("Heads: %d\tTails: %d\n", heads, tails);
}
int flip()
{
result = 1 + rand() % 2;
if (result == 1)
return 1;
if (result == 2)
return 0;
return NULL;
}
syntax error: ')' (line 10)
'counter': undeclared identifier (15, 23)
'heads': undeclared identifier (19, 23)
't': undeclared identifier (10, 10)
syntax error: missing ')' before 'type' (line 10)
syntax error: missing ';' before '{' (line 11)
syntax error: missing ';' before 'type' (9, 10, 10, 10)
Thanks for any response.
Soluzione
Altri suggerimenti
Here is a modified code which runs fine with me in eclipse :
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int result;
int flip();
int main(void)
{
srand(time(NULL));
int heads = 0;
int tails = 0;
unsigned counter;
for(counter = 1; counter <= 100; counter++)
{
result = flip();
if(result == 1)
{
printf("Heads\n");
heads++;
}
else
{
printf("Tails\n");
tails++;
}
}
printf("Heads: %d\tTails: %d\n", heads, tails);
return 0;
}
int flip()
{
result = 1 + rand() % 2;
if (result == 1)
return 1;
if (result == 2)
return 0;
}
Mistakes: In main , you forgot 'return 0 ' statement. In flip function you wrote 'return NULL' which should not be there. Try this code in vs.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void){
int heads = 0,tails = 0;
unsigned int counter = 1;
int result = 0;
srand(time(NULL));
for(counter = 1; counter <= 100; counter++){
result = rand()%2;
if(result == 1){
heads++;
}
else{
tails++;
}
}
printf("Heads: %d\tTails: %d\n", heads, tails);
return 0;
}
