Application Of Stack Adt – Balancing Parenthesis Data Structure Algorithm

Stack Adt Balancing Parenthesis Algorithm it has header file Balance.h it contains stack structure , STACK create(),int isempty(STACK s),int isfull(STACK s),void push(char x, STACK s),void pop(STACK s),char check(STACK s),int top(STACK s) by using these function and data variable it will perform Balancing.

OUTPUT Data structure Lab Source code Programming algorithm - CS1152 c/c++
Enter the Expression: {[(a+b)*(p-q)]/(x/y)}
Balanced Parenthesis
Enter the Expression: {[(a+b)*(p-q])/(x/y)}
Imbalanced Parenthesis
