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 two operands from the Stack Create a string by concatenating the two opera...
Input : (A - B/C) * (A/K-L) Output : *-A/BC-/AKL 分析: 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...
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...

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...
This implements the changes discussed in #81: prefix/postfix have been replaced with valueprefix/valuepostfix These identifiers are fully separate from popupprefix/popuppostfix
