After traversing the entire string, remaining operators are popped from the stack and added to the postfix string. Example Usage of the infix_to_postfix Function Let's consider the algorithm's operation using the expression -2*ln(x)/(4*-2*sin(5*x)). Replacement of Unary Minuses: Original...

22. If thepostfixexpression was correctly formed, the stack should be empty. 若后缀表达式格式正确,那么堆栈应该为空。 youdao 23. How is thepostfixand prefix increment operator evaluated in an expression? 后缀和前缀增量运算符表达式中的评价如何?
s.push(c); } } // append any remaining operators in the stack at the end of the postfix expression while(!s.empty()) { postfix.push_back(s.top()); s.pop(); } // return the postfix expression returnpostfix; } intmain()
pop two numbers from the stack, do the operation, and put the result back on the stack (The top number on the stack is the operand on the right) The result is the only thing on the stack when done –If there’s more than one thing, there was an error in the expression * 5 / ...

Note 1: for security reasons, the virtual(8) delivery agent disallows regular expression substitution of $1 etc. in regular expression lookup tables, because that would open a security hole. It means we must add each mapping explicitly in the vmailbox hash file. (My personal opinion is that...
