notes stacks are frequently used for converting infix form into equivalent prefix and postfix forms the whole logic is same as for infix to postfix exceptbefore traversing the string reverse it by strrev(function and then process as beforebut instead of printing the expression take output in another stack and then print the stackat last reverses the string str process of conversion strrev (strprefix expression consider the following example infix expression - after reversing it - now apply the logic of infix to postfix conversion and store the output in another stack operator stack output stack now on printing the stack we havea which is prefix expression here is implementation for converting infix into postfix /convert infix expression into corresponding postfix expression */maximum length of the input expression allowed is characters *#include #include #include #include typedef struct char data[ ]/array to hold stack contents *int top/top of the stack pointer *}stk/function prototypes *void initstack(stk *stack)void get_infix(char infix[])void converttopostfix(char infix[]char postfix[])int isoperator(char )int precedence(char operator char operator )int pred_level(char ch)void push(stk *stackchar value) lovely professional university
