A small command-line calculator that builds a computational graph based on the expressions you enter and computes the value of the specific node

• help : prints all commands with their descriptions
• set [variable-name] [definition] : adds (or reassign) the definition (or expression) of the variable-node named 'variable-name'
• exit : exits calculator
• showvars : shows all variables with their assigned-status and the last assigned definition
• info : shows different information about graph engine's current state
• evaluate [variable-name] : evaluates the value of the variable-node named 'variable-name'

Project is created with:

• C language
