This program evaluates complex mathematical expressions provided by the user. It supports standard arithmetic operators, trigonometric functions (sin, cos), logarithmic functions (log), and the ...

Using a single stack we convert from infix to postfix. We first check for any arithmetic errors that might cause problems later in the calculation. Then we check for negatives, operators, and digits ...

An algorithm to convert infix expression into a postfix expression using “Stack”. The purpose of stack is to reverse the order of the operators in the expression as it is used to hold operators rather ...
