Thepostfix-expressionabove may be aprimary expressionor another postfix expression. Postfix expressions group left to right, thus allowing the expressions to be chained together as follows: C++ func(1)->GetValue()++ In the above expression,funcis a primary expression,func(1)is a function postfix...

Here is what you need to do: Given an integer postfix expression, you must calculate and print its value. 输入 Each input will consist of a single test case. Your program will be run multiple times on different inputs. A single input line will contain a postfix expression containing single...
“uncaught syntaxerror: invalid left-hand side expression in postfix operation”是一个JavaScript运行时错误,通常发生在尝试对一个不合适的表达式执行后缀运算(如自增++或自减--操作)时。在JavaScript中,后缀运算符需要一个左值(lvalue),即可以出现在赋值语句左侧的表达式。如果后缀运算符的左侧不是一个有效的左值,...

To input the initial string to be processed, functions described in the files input_expr.c and input_expr.h are used. The main input function: input_expr(char **const str): Takes a pointer to a string where the entered expression will be stored. Returns the length of the string. Possib...
