Please answer in C++ Define a structure called Date with month, day and year as its only data members, Time with hour and minute as its only members and Event with desc (a c-string for description of maximum size 80), date (of type Date) and time (of type Time). Write a readEvents() function that will keep asking the user if he or she wants to add a new event. As long as the user answers with a 'y' or 'Y', allocate memory dynamically for an Event structure, storing the pointer returned by new in the array of Event pointers and then read the Event data from the keyboard and store them in the Event just created. Dates should be entered like 5/21/20 and times as 10:15. When finished entering the Events, the function will return the number of Events entered. Write a sort-desc() function to sort the Events by their description by rearranging the pointers (rather than the structures), by passing it the array of pointers and the number of Events created. Use a swapPtrs() function to swap…
WAP C++ program, in which the user inputs a character value, and the program prints "Digit" in the output if the character is a digit, prints "Alphabet" if the character is an alphabet. Otherwise, the program, prints "Other".
C++ Write a program that takes as input an arithmetic expression followed by a semicolon ;. The program outputs whether the expression contains matching grouping symbols. For example, the arithmetic expressions {25 + (3 – 6) * 8} and 7 + 8 * 2 contains matching grouping symbols. However, the expression 5 + {(13 + 7) / 8 - 2 * 9 does not contain matching grouping symbols. If the expression contains matching grouping symbols, the program output should contain the following text: Expression has matching grouping symbol If the expression does not contain matching grouping symbols, the program output should contain the following text: Expression does not have matching grouping symbols.

C Program to convert Decimal to Binary Decimal to binary in C: We can convert any decimal number (base-10 (0 to 9)) into binary number(base-2 (0 or 1)) by c program. Decimal Number Decimal number is a base 10 number because it ranges from 0 to 9, there are total 10 digits between 0 to 9. Any combination of digits is decimal number such as 23, 445, 132, 0, 2 etc. Binary Number Binary number is a base 2 number because it is either 0 or 1. Any combination of 0 and 1 is binary number such as 1001, 101, 11111, 101010 etc.
