Multidimensional Arrays

• You are allowed to make arrays of any type, including arrays! These arrays of arrays are called multidimensional arrays, and are declared and used like this:

  #define NUM_CITIES 12
  #define NUM_DAYS 365
  
  int main()
  {
    float rainFall[NUM_CITIES][NUM_DAYS];
    int i, j;
  
    for ( i = 0; i < NUM_CITIES; i++ )
       {
       for ( j = 0; j < NUM_DAYS; j++ )
          {
          printf( "Enter in the rain fall for city #%d, day #%d: " );
          scanf( "%f", &( rainFall[i][j] ) );
          }
       }
  
  }
  

• How would you declare and use a four-dimensional array?
