- C program to Check for balanced Parentheses in an Expression using Stack. - Write a program in C to Check if Expression is correctly Parenthesized. - Given a string of ' { ' and '\}' parentheses characters, we have to check whether parentheses are in correct order or not. - Valid Expressions - {{{},{{{}},{{}}} - Invalid Parenthesis Expressions - Number of opening parenthesis('\{') must be same as number of closing parenthesis(' '\}'). - For every ' } ', there must be a corresponding { ' before. - At any moment of time number of ' { ' must be >= number of ' }. Output - Enter a string of 6 parenthesis (Program Run 1 of 2): - {{{}}} - Stack full, last value entered (stack top): } - Valid Parenthesis Expression - Enter a string of 6 parenthesis (Program Run 2 of 2): - \{\}{{} - Stack full, last value entered (stack top): \{ - Invalid Parenthesis Expression
