C++ Programming Example: Write a program that inputs the current price of gas and electricity per unit. Give each item’s rate with an increment of 20%. The program computes the new price of gas and electricity using cin cout stream objects:

c++ Stream objects C++ Programming Example

C++ Programming Example: write a program which calculate the employee dearness allowance, medical allowance, house rent allowance and calculate the gross salary and display using cin cout stream objects:

25% dearness allowance.

15% medical allowance.

45% house rent allowance.

formula:

gross salary= basic pay + dearness allowance + medical allowance + house rent.
