C-Interpreter

This project is a simple interpreter that executes instructions and prints the result of execution using C programming language.

System Description:

Accept a text file as source code and Checks if it exists
Scan the line containing the variable name and the expression / value.
Validates RHS & LHS of the equation.
Evaluating the RHS.
Inserting the variable name & it’s value into BST
After going through all the lines in source code, we copy the tree into heap.
In order traversal for BST was used in order to sort the variables by names.
Heap sort Algorithm was used in order to sort the variables by values.

User Manual:

Create text file named src.txt in the same directory containing the equations
Form of Equations is not restricted by spaces or -ve signs. Some valid expression examples:

X = 12.5
Z = X*Y/5
K = 10.5+ (Z-2.5)/(X+Y)

Notes to avoid :

Left hand side should contain only one variable.
Invalid expressions example :

(x+y)/(3+1

Invalid expression example :

Invalid Symbol , Missing (=).

Output will be printed twice as follows:

Sorted according to variable name
Sorted according to the variable value
