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
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...

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...
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...
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 from operand stack, pop operator from operator stack and ...
prefix and postfix are unary operators in c++ when you write i++ in loop it is known as postfix notation and when you write ++i it is known as prefix notation eg:- for (int i=0;i <9;i++) it is(i++) is postfix notation and you can use them at other places also to increment...
1st case - j = ++i + i++; j = 4 + 4; In the above case ++i has modified the value of 3 to 4 but i++ has no effect since it is a post fix. Prefix means the value is first incremented and then the value is stored in the variable assigned but where as in postfix the va...
