Program
Explanation:
Program is like a set of instructions that helps hardware process data into information.
Every hardware needs a program to process data into information.
For example take the example of a data processing software like MS Excel.
You open a spreadsheet and enter some data into your sheet. and then ask the program to do some calculations with this data and give you output results. The spreadsheet software does this processing in the background for you and provides you the results.
Without program a hardware doesn't know what to do with the data. Therefore, a program is like a instruction set that guides the hardware what to do with the data.
Note: The terms software and program are usually used together but there is a difference between software and program
A software is a generalized term and program is more like a specific term.
software can be made up of several different programs which performs many different tasks. On the other hand, a program only carry out a specific task or set of instructions.

Answer:
In Python:
Unit_Cost = 200
Cost50 = 50 * Unit_Cost
print("Cost of 50 items: Rs."+str(Cost50))
Explanation:
This initializes the unit cost to 200
Unit_Cost = 200
This calculates the cost of 50 of such items
Cost50 = 50 * Unit_Cost
This prints the calculated cost
print("Cost of 50 items: Rs."+str(Cost50))
