The language is created using parse tree,lexical generators like Bison and Lex.
features such as evaluating an expression , basic arithmetic operations(+,-,*,/) , if condition , while loop
It considers context free grammar(CFG)
The CFG used in this language is :
<expr> := [ <op> <expr> <expr> ] |
<symbol> | <value>
<symbol> := [a-zA-Z]+
<value> := [0-9]+
<op> := ‘+’ | ‘*’ | ‘==‘ | ‘<‘
<prog> := [ = <symbol> <expr> ] |
[ ; <prog> <prog> ] |
[ if <expr> <prog> <prog> ] |
[ while <expr> <prog> ] |
[ return <expr> ]
To run this program use:
bash run1
./runit
To clear all the object files and the other generated files use:
./clear
