int main()
{
    char weight[4];
    int w;
 
    printf("Enter your weight:");
    gets(weight);
    w=atoi(weight);
 
    printf("Here is what you weigh now: %i\n",w);
    w--;
    printf("w++: %i\n",w);
    w--;
    printf("w++: %i\n",w);

    return(0);
}

Enter your weight:123
      Here is what you weigh now: 123
      w++: 122
      w++: 121
