Write in C program and and show a drawing as well.

G = (N, T, P, S) where:

N = {task, expr, term, factor, value, number, digit}

T = {=, +, -, *, ^, (, ), 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

NOTE: BNF is P

P = {task -> expr =

expr -> expr + term | expr term | -expr | term

term -> term * factor | factor

factor -> factor ^ value | value

value -> (expr) | number

number -> number digit | digit

digit -> 0 | 1 | 2 | 3 | 4| 5 | 6 | 7 |8 | 9

}

S = {task}
