Algorithm of Calculator Program
Declare 4 variables - num1, num2, result, opt.
The variables num1 and num2 are for storing the values or operands, for storing the calculation result, and opt to take the operator as inputs.
Take inputs of the operands, operator..
You need to declare variables before you can use them.
Use operators + - * and / to perform mathematical operations.
Division ( / ) of integers will truncate (not round) the result. printf uses " %d " to output an integer variable..
Programmable calculators allow the user to write and store programs in the calculator in order to solve difficult problems or automate an elaborate procedure..
C means "Clear" (more) It clears the display and any partial calculation..
The purpose of a calculator is to do correct calculations, and to do so efficiently.
It is clear that a calculator should relieve the user of the need to do mental operations and of the need to rely on paper, so far as possible..
