C++

Create a program that when an arithmetic expression containing numbers and the binary operators +, -, *, /, and % is passed, it will return a string that displays a step-by-step simplification of the expression, until you are left with the numerical result.

EX:

"2+3*4-5 = 2+12-5 = 14-5 = 9"

string methods used:

• string fill constructor
• find_first_of method
• replace method
• substr method
