Question

Count Below and Above Average Numbers

Use the following main( ) function:

const int maxSize = 50;

int main()

{

int l, u, n, A[maxSize], le, mo;

input(l, u);

cout << "How many numbers you want to generate < 50: ";

cin >> n;

generateNumbers(n, l, u, A);

le = countLessMore(n, A, mo);

cout << "There are " << le << " numbers less than the average and "

   << mo << " numbers more than the average" << endl;

return 0;

}

Define the following functions:

void input(int &, int &) // reads the lower L and upper U limits of an interval and

// validates that the limits satisfy 0 < L < U < 100.

void generateNumbers(int, int, int, int []) // generates n < 50 random numbers between L and U // inclusive. The function saves the random numbers

// in an array.

int countLessMore(int, int [], int &) // calculates and prints the average of the n random // numbers, it also counts how many numbers are less // than the average and how many are greater than or // equal to the average.

Format the output as in the sample input/output below and make sure that the program generates different numbers in each run:

Enter the value of lower, o< lower < 100: -6 Enter the value of lower, o< lower < 100: 27 Enter the value of upper, 27 < upper <= 100: 13 Enter the value of upper, 27 < upper <= 100: 231 Enter the value of upper, 27 < upper <= 100: 78 How many numbers you want to generate < 50: 9 The generated number are: 29 35 31 63 75 35 70 52 61 The average is 50.1111 There are 4 numbers less than the average and 5 numbers more than the average
