Lab 11

George formed a table for his electricity, telephone, and water bills for 
2001. The table consists of 12 rows and 3 columns. The first row consists 
of the electricity bill followed by the telephone bill followed by the 
water bill for the month of January. The second row consists of the 
electricity bill followed by the telephone bill followed by the water bill 
for the month of February. The third row consists of the electricity bill 
followed by the telephone bill followed by the water bill for the month of 
March. And so on. Write a program to read the elements of the table from 
the keyboard (elements should be of type float). Your program should have 
a function (call it F). Function F should have 4 parameters; a 
two-dimensional array A (assume it has 12 rows and 3 columns), e: a 
reference parameter of type float, t: a reference parameter of type float, 
and w: a reference parameter of type float. Function F should calculate: 
the average of the first column (i.e. column 0) of A and return it via 
parameter e, the average of the second column (i.e. column 1) of A and 
return it via parameter t, and the average of the third column (i.e. 
column 2) of A and return it via parameter w. Pass the table to function F 
and then display the average electricity, telephone, and water bills for 
2001.
