Math-Expression-Solver-with-Graph

Program in C which parse an expression with one argument x and draw its graph in terminal

Tokenizer parse the expression and create a tree of operations using shunting-yard algorithm.

Graph is drawn using ASCII characters. In range 0..4 * Pi on the x-axis and -1..1 on the y-axis. The graph is scaled to 25x80 terminal size. X-axis is on the 13th row and y-axis is reversed upside down.

List of operations:

• + = +
• - = - binary
• ~ = - unary
• * = *
• / = /
• ( = (
• ) = )
• s = sin(x)
• c = cos(x)
• t = tan(x)
• g = ctg(x)
• q = sqrt(x)
• l = ln(x)
• v = if value is stored
