Given main(), create the Calculator struct that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear. The struct has one data member called value for the calculator's current value. Implement the Calculator struct and related function declarations in Calculator.h, and implement the related function definitions in Calculator.c as listed below: • Calculator InitCalculator() - initialize the data member to 0.0 • Calculator Add(double val, Calculator c) - add the parameter to the data member • Calculator Subtract(double val, Calculator c) - subtract the parameter from the data member Calculator Multiply(double val, Calculator c) - multiply the data member by the parameter Calculator Divide(double val, Calculator c) - divide the data member by the parameter Calculator Clear(Calculator c) - set the data member to 0.0 • double GetValue(Calculator c) - return the data member Given two double input values num1 and num2, the program outputs the following values: 1. The initial value of the data member, value 2. The value after adding num1 3. The value after multiplying by 3 4. The value after subtracting num2 ● ● ● 5. The value after dividing by 2 6. The value after calling the clear() method Ex: If the input is: 10.0 5.0 the output is: 0.0 10.0 30.0 25.0 12.5 0.0 1 #include 2 #include 3 4 #include "Calculator.h" 5 6 // TODO: Define functions 7 // 8 9 /* Type your code here. */ 1 #ifndef CALCULATOR_H_ 2 #define CALCULATOR_H_ Current file: Calculator.c InitCalculator (), Add(), Subtract(), Multiply(), Divide (), Clear(), GetValue() 10 #endif 11 Current file: Calculator.h // TODO: Define the Calculator_struct 5 6 // TODO: Declare functions 7 // 8 9 InitCalculator (), Add(), Subtract(), Multiply(), Divide (), Clear(), GetValue()

Given main(), create the Calculator struct that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear. The struct has one data member called value for the calculator's current value.
Transcribed Image Text:Given main(), create the Calculator struct that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear. The struct
has one data member called value for the calculator's current value.
Implement the Calculator struct and related function declarations in Calculator.h, and implement the related function definitions in
Calculator.c as listed below:
• Calculator InitCalculator() - initialize the data member to 0.0
• Calculator Add(double val, Calculator c) - add the parameter to the data member
• Calculator Subtract(double val, Calculator c) - subtract the parameter from the data member
• Calculator Multiply(double val, Calculator c) - multiply the data member by the parameter
• Calculator Divide(double val, Calculator c) - divide the data member by the parameter
• Calculator Clear(Calculator c) - set the data member to 0.0
• double GetValue(Calculator c) - return the data member
Given two double input values num1 and num2, the program outputs the following values:
1. The initial value of the data member, value
2. The value after adding num1
3. The value after multiplying by 3
4. The value after subtracting num2
5. The value after dividing by 2
6. The value after calling the clear() method
Ex: If the input is:
10.0 5.0
the output is:
0.0
10.0
30.0
25.0
12.5
0.0
