Requirements:

$1.$ The application should be able to generate Electric bill for all the customers individually.

$2.$ It should be possible to print the electric bill for a specific customer upon request.

c$)$ Current month reading along with electric meter number.

$5.$ Array of structures are to be used to store the data read from the file.

$6.$ Dynamic memory allocation has to be used to allocate memory for the array of structures.

$7.$ It should be menu driven and user$-$friendly.

$8.$ User$-$defined functions need to be used wherever possible to reduce the complexity of the program

with the introduction of modular structure.

$9.$ Tariff Rates given in the table $1$ should be used for the calculation.
