1. To convert an infix expression below into postfix using stack. a + g * c + (b * d * e + a) * f + g * (h + i) + a

2. Evaluate the generated postfix expression using stack with the values given below. a = 5.6, b = 5.1, c = 8.2, d = 3.3, e = 1.5, f = 6.7, g = 4.2, h = 0.3, i = 2.3

Datafile is located in under files on canvas.

Output Requirements: 1. Print infix expression contained in the input 2. Print the postfix expression generated using stack. 3. Print the result from evaluating postfix expression using stack.
