Mike likes to use _(underscores) and ! (exclamation points) in his written communications. Write a program characters.c that computes the number of underscores and exclamation points in an input sentence. The program should include the following function. Do not modify the function prototype.

void count(int* num_, int* num_exclamation);

The count function asks the user to enter a sentence. Use getchar() function (getchar() is covered in chapter 7) to read in the input. The user input ends with the user pressing the enter key (a new line character).

The count function takes two parameters of int *. The num_ parameter points to a variable in which the function will store the number of underscores. The num_exclamation parameter points to a variable in which the function will store the number of exclamation point.

The main function calls the count function. It should also contain the printf statements that display the result.

Example input/output: Enter a sentence: _Hi_there!!! Output: There are 2 underscores and 3 exclamation points in the sentence.
