Data Structures and Data Organization Submissions Fall 2020-2021 Lab Work #5 (ONLY SUBMIT YOUR C or CPP SOURCE CODE, NO COMPRESSED FILE IS ACCEPTED) Your program should; 1 - Accept the infix expression string from the user 2 - Execute Parenthesis Checker and if paranthesization is ok; 3 - Execute Infix to Postfix conversion algorithm 4- Show the evaluation result of the entered expression. Remember, you should display the result f every step on the monitor. Labwork 5 Laboratory Works Laboratory work will be done at the laboratory. Consider the following stack structure: struct stack int items[50] int top: Implement the following basic functions ofthe stack structure. Taskl: Write down a complete C/C++ program to implement parenthesis checker algorithm The algorithm for this procedure as follows: Struct stacks s=empty_stack// initialize the stack valid=true while( not read entire string) { read the next symbol (symb) of the string if(symb== (symb== [ symb == {{ ) push(&s, symb) if(symb==) | symb == ']" || symb== }^ ). if(empty_stack) valid=false else{ i=pop(&s) if(i is not the matching opener of symb) valid=false } 3 if('empty_stack) vald=false
