i need help in my project
can anyone help me with my School project..since

My Teacher told me to make a simple basic compiler that has lexical analysis features


so it means onc you type an expression on a textbox..and verify that line

it will separate Identifier,operator,assignment operator and number


so lets say you type sum=a+b

then on the ListBox it will show

sum is an identifier
= is an Assignment Operator
a is an identifier
+ is an Operator
b is an identifier


just like that and if i inputted sum = 1 + 2 then it will show

sum is an identifier
= is an Assignment Operator
1 is a number
+ is an Operator
2 is a number

after that on the second listbox it will show

Sum = 3 (since 1+2 is inputted on the textbox)

I hope someone could help me and provide the easiest code as possible
