Description of the assignment: Your program should read in a set of grades (that are all integers) entered by the user. The user will signify the end of the list of grades by entering -999. Do NOT process this value. You can assume that the user will enter at least three grades and not more than 100 grades, all of which will be integers in between 0 and 100, inclusive. For the set of grades, your program should compute the minimum value, print this out to two decimal places and remove it from the data. Then your program should compute the maximum value, print it out to two decimal places and remove it from the data. Then, your program should calculate the mean and standard deviation for the remaining set of grades, and print these out to two decimal places. Finally, a histogram for this data (without the highest and lowest grades) should be printed out as well. Your program should include the following functions: void readGrades (double grades [], int *n); /* This function reads an unknown number of grades (maximum of 100) into the array grades and counts the data items that have been read. You are not supposed to prompt the user to enter the grades. Just use scanf to read in the grades. The end of the input is represented by a negative number -999 */ Preconditions: An empty array which is initialized to 0 must be passed to the function. Postconditions: Array holds the input values and n is the effective size of the array (i.e the number of data items read) */ void frequency (double grades[], int n) /* Given an array of real numbers, this function finds out frequency (number of students) for each interval 0-4, 5- 9,...,95 - 99, 100 prints out the frequency values and plots the histogram */ int maximum (double grades [], int n) ; /* Given an array of real numbers and the effective size of the array (i.e. count of the numbers in the array), this
