Match each data operator with its function:
OFFSET
Returns the number of the elements in an array.
TYPE
Returns the size of a variables byte.
SIZEOF
Returns the memory adress of a variable.
LENGTHOF
Returns number of bytes used in an array.
TRUE OR FALSE
You should not pass a one-dimensional array to a function.
Passing an array by reference is more efficient than passing it by value.
The quick sort algorithm provides a quick and easy way to sort the items stored in an array, as long as the number of items is relatively small—for example, fewer than 50.
The variables in an array may be stored in non-consecutive memory locations in the computer’s internal memory.
It takes longer for the computer to access the information stored in a disk file, than in an array in memory.
Median Function – In statistics, the median of a set of values is the value that lies in the middle when the values are arranged in sorted order. If the set has an even number of values, the median is the average of the two middle values.
Your program should start with two arrays of integers containing the following values:
Even numbered array: 17 32 45 68 99 101 67 89 22 27
Odd numbered array: 17 32 45 68 99 101 67 89 22
Using a sort function of your choice, first sort the arrays. NOTE: you may use the Standard Template Library sort function or your own sort function.
Then, write a function that determines the median of a sorted array. The function should take an array of numbers and an integer indicating the size of the array and return the median of the values in the array. The same function should be called twice – once for the even array and once for the odd array.
Your program should also have a printArray function that can be used to print the sorted array. (It…

- (Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.arrow_forward(Electrical eng.) Write a program that specifies three one-dimensional arrays named current, resistance, and volts. Each array should be capable of holding 10 elements. Using a for loop, input values for the current and resistance arrays. The entries in the volts array should be the product of the corresponding values in the current and resistance arrays (sovolts[i]=current[i]resistance[i]). After all the data has been entered, display the following output, with the appropriate value under each column heading: CurrentResistance Voltsarrow_forward(Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forward
