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.
2- The factorial n! of a positive integer n is defined as n! = 1*2*3 . .. * (n-1) * n Where 0! = 1 Write a function to calculate the factorial of a number. Argument: A number n of type unsigned int. Returns: The factorial n! of type long double. Write two versions of the function, where the factorial is • calculated using a loop calculated recursively Test both functions by outputting the factorials of the numbers 0 to 20.
