Thread: Program runs on mac but not on windows

Code:

#include <stdio.h>
#include <string.h>
void leftRotate(int a[], int t, int n);
void leftRotatebyOne(int a[], int n);
void printArray(int a[], int n);
void rightRotatebyOne(int a[], int n);
void rightRotate(int a[], int t, int n);


int main(){
int n;
int i;
char dir[1];
int k;
int t = 0;




int a[1000];
int new[1000];


printf("Enter the amount of numbers in the array:\n");
scanf("%d",&n);
printf("This are the elements in your array:\n");
for (i=0; i < n; i++)
{
	a[i]=(rand()%100);
	printf("%d ",a[i]);
}
printf("\n");
printf("Shift L or R?\n");
scanf("%s",dir);
printf("How many times?\n");
scanf("%d",&t);


if (*dir=='L')
{
	leftRotate(a, t, n);
	printArray(a, n);
}
else if (*dir=='l')
{
	leftRotate(a, t, n);
	printArray(a, n);
}
else if (*dir=='R')
{
	rightRotate(a, t, n);
	printArray(a, n);
}
else
{
	rightRotate(a, t, n);
	printArray(a, n);
}


 return 0;
}
void leftRotate(int a[], int t, int n)
{
  int i;
  for (i = 0; i < t; i++)
    leftRotatebyOne(a, n);
}
void leftRotatebyOne(int a[], int n)
{
  int i, temp;
  temp = a[0];
  for (i = 0; i < n-1; i++)
     a[i] = a[i+1];
  a[i] = temp;
}
void printArray(int a[], int n)
{
  int i;
  for(i = 0; i < n; i++)
    printf("%d ", a[i]);
}


void rightRotate(int a[], int t, int n)
{
  int i;
  for (i = 0; i < t; i++)
    rightRotatebyOne(a, n);
}
void rightRotatebyOne(int a[], int n)
{
  int i, temp;
  temp = a[n-1];
  for (i = (n-1); i > 0; i--)
     a[i] = a[i-1];
  a[i] = temp;
}

Runs and compiles on mac with no issues, but when comp and run it on windows it doesn't output the resultant array... Any help would be appreciated.

Thank you salem.
