Machine Problem. Create an app for an E×ρréššion tree generator and evaluator employing the C language project files (multiple files - .cbp, .h, .c, .exe). Use the appropriate data structure and algorithm implementations to accomplish these functions. Your program should be able to:
- Allow the user to input a string of operators and operands as shown in the example below.
- Ex. Z = 5x^3 + ((7xy^2 – 3x) + 9)
- Show the equivalent E×ρréššion tree in graphical form following the rules that we defined in our lecture discussions
- Identify all the variables of the E×ρréššion and ask the user to input the actual values for each
- Ex. Input x = 4, Input y = 6
- Evaluate the E×ρréššion based on the actual values inputted
- Ex. z = 5(4)^3 + ((7(4)(6)^2 – 3(4)) + 9)
z =
To create an app for an E×ρréššion tree generator and evaluator in C, you will need to follow a structured approach. Here's a high-level overview of how you can tackle this machine problem:
1.
Define Data Structures:
- Define data structures to represent the E×ρréššion tree nodes, variables, and operators. You can use structs to define these data structures.
2.
Parsing the Input:
- Implement a parser that can read and tokenize the input E×ρréššion provided by the user. Break down the E×ρréššion into individual operands, operators, and variables for further processing.
3.
Build the E×ρréššion Tree:
- Use the parsed tokens to construct the E×ρréššion tree following the rules discussed in your lectures. Each node in the tree should represent an operator or operand.
4.
Display the E×ρréššion Tree:
- Implement a function to display the E×ρréššion tree in a graphical form. You can use ASCII art or any graphical representation that suits your project requirements.
5.
Variable Input:
- Identify and extract all variables used in the E×ρréššion. Prompt the user to input actual values for each variable.
6.
Evaluate the E×ρréššion:
- Implement an evaluator function that recursively evaluates the E×ρréššion tree based on the actual values provided by the user. Perform the necessary calculations following the order of operations.
7.
Output the Result:
- Display the evaluated result of the E×ρréššion after substituting the actual variable values into the E×ρréššion.
8.
File Structure:
- Organize your project files (.cbp, .h, .c) in a structured manner. Divide your code into multiple files based on functionality to maintain clarity and modularity.
Remember to use appropriate algorithms and data structures such as stacks or recursion to handle the E×ρréššion tree operations efficiently.
