Given a Postfix expression, convert it into a Prefix expression. 分析: Read the Postfix expression from left to right If the symbol is an operand, then push it onto the Stack If the symbol is an operator, then pop
If it is an operand, then push it into operand stack. If it is an operator, then check if priority of current operator is greater than or less than or equal to the operator at top of the stack. If priority is greater, then push operator into operator stack. Otherwise pop two operands...
To convert an infix to Prefix, first we’ve to know how to convert Infix to postfix notation. Initially we’ve astringS which represent the expression in infix format. Reverse thestringS. After reversing A+B*C will become C*B+A. Note while reversing each ‘(‘ will become ‘)’ and e...
Traverse the infix expression and check if given character is an operator or an operand. If it is an operand, then push it into operand stack. If it is an operator, then check if priority of current operator is greater than or less than or equal to the operator at top of the stack. ...

I've figured out the basic code for converting a prefix expression to infix expression but can't figure out how to place the brackets. Here's my code:int main(int argc, char* argv[]) { char input; char symb; Stack S; char String[50] = "/0"; int i=0;//cout<<endl<<"Prefix...

Is it reasonable to use the prefix increment operator ++it instead of postfix operator it++ for iterators?Andrey Karpov
