Thread: Problem in the loop

I am in the early stages of creating a game of fifteen but i am having a problem. When i run this program i can do "up" and "down" all day long, but when i try "left" or "right" or type anything else in for that matter it performs "down".

I know there is a simple answer to this, but i cant seem to find the problem and its been driving me nuts!

if you have a better idea of how i should be using functions in this code feel free to let me know

thanks in advance

heres the code

Code:

#include <stdio.h>
#include <string.h>

void show(int numbers[][4]);
void move(char input[]);

main()
{
  int numbers[4][4]={15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 1, 2, 0};
  int correct[4][4]={0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15};
  char input[5];
  int x, y, tmp;
  x=y=3;
  show(numbers);
  move(input);
  while(numbers != correct)
  {
    if(strcmp(input, "up") == 1)
    {
      tmp=numbers[y][x];
      numbers[y][x]=numbers[--y][x];
      numbers[y][x]=tmp;
    } 
    else if(strcmp(input, "down") == 1)
    {
      tmp=numbers[y][x];
      numbers[y][x]=numbers[++y][x];
      numbers[y][x]=tmp;
    }
    else if(strcmp(input, "left") == 1)
    {
      tmp=numbers[y][x];
      numbers[y][x]=numbers[y][--x];
      numbers[y][x]=tmp;
    } 
    else if(strcmp(input, "right") == 1)
    {
      tmp=numbers[y][x];
      numbers[y][x]=numbers[y][++x];
      numbers[y][x]=tmp;
    }
  show(numbers);
  move(input);
  }
}


void show(int num[][4]) /***Display The Layout of the Game***/
{
  int i, j;
  for(i=0; i <= 3; i++) 
  {
    for(j = 0; j <= 3; j++)
      printf("&#37;5d", num[i][j]);
    printf("\n\n");
  }
}


void move(char input[]) /***inputing what space they want to switch with 0***/
{
  char c;
  int i;
  printf("Please enter in the space you want to switch with 0 by indicating \"up\", \"down\", \"left\" or \"right\"\n");
  for(i=0; c!='\n'; i++)
    input[i]=(c=getchar());
  input[i]='\0';
}
