A calculator is an electronic device that is used to perform arithmetic operations like addition, subtraction, multiplication, division, etc. You are requested to develop an embedded software of a calculator with following specifications: a. This program takes an arithmetic operator (+, -, *, /) and two operands as the input. b. It also checks whether the user wants to quit the program, if yes then terminate the program execution. For this, you can use a special character and tell the user about it, like here we used "X". C. The arithmetic operation is performed based on the operator and two operands inserted by user in (a). d. Display the complete arithmetic operation which includes the 2 operands, the arithmetic operator, and the computation result. Figure 5 shows samples of expected program execution output display for your reference in solution development. Enter an operator (+, -, *, /) or 'x' to exit: + Enter two operands: 7.3 8.9 7.30 +8.90 = 16.20 Enter an operator (+, -, *, /) or 'x' to exit: - Enter two operands: 8.5 12.34 8.50 12.34 = -3.84 Enter an operator (+, -, *, /) or 'x' to exit: * Enter two operands: 1.5 100 1.50 100.00 = 150.00 Enter an operator (+, -, *, /) or 'x' to exit: / Enter two operands: 8 3 8.00/3.00 = 2.67 Enter an operator (+, -, *, /) or 'x' to exit: x Exit the program! Figure 5 1. Sketch a flowchart which provides solution according to the given specification and requirement. 2. Based on your flowchart, derive the complete C code to deliver the simple calculator.

Question
Transcribed Image Text:A calculator is an electronic device that is used to perform arithmetic operations like addition, subtraction,
multiplication, division, etc. You are requested to develop an embedded software of a calculator with
following specifications:
a. This program takes an arithmetic operator (+, -, *, /) and two operands as the input.
b. It also checks whether the user wants to quit the program, if yes then terminate the program
execution. For this, you can use a special character and tell the user about it, like here we used
"X".
C.
The arithmetic operation is performed based on the operator and two operands inserted by user
in (a).
d. Display the complete arithmetic operation which includes the 2 operands, the arithmetic
operator, and the computation result.
Figure 5 shows samples of expected program execution output display for your reference in solution
development.
Enter an operator (+, -, *, /) or 'x' to exit: +
Enter two operands: 7.3 8.9
7.30 +8.90 = 16.20
Enter an operator (+, -, *, /) or 'x' to exit: -
Enter two operands: 8.5 12.34
8.50
12.34 = -3.84
Enter an operator (+, -, *, /) or 'x' to exit: *
Enter two operands: 1.5 100
1.50
100.00 = 150.00
Enter an operator (+, -, *, /) or 'x' to exit: /
Enter two operands: 8 3
8.00/3.00 = 2.67
Enter an operator (+, -, *, /) or 'x' to exit: x
Exit the program!
