A simple variable, also called a scalar variable, is one that is unrelated to any other variable in the computer’s internal memory

True or False. A simple variable, also called a scalar variable, is one that is unrelated to any other variable in the computer’s internal memory. The bubble sort algorithm gets its name from the fact that as the larger values drop to the bottom of the array, the smaller values rise, like bubbles, to the top. Programmers use arrays to temporarily store related data in the internal memory of the computer. Different variables in the same array may have different data types. The elements in an array can be used just like any other variables. When an array is sorted in ascending order, the first element contains the largest value and the last element contains the smallest value. When passing an array by reference in C++, you do not include the address-of operator before the formal parameter’s name in the function header. You distinguish one variable in a one-dimensional array from another variable in the same array using a unique integer, called a subscript. You may use either an assignment statement or the extraction operator to enter data into an array element. Arrays in C++ are automatically passed by value. When declaring an array, you enclose the number of elements in the array in braces ({}). At times, a program might need to arrange the contents of an array in either ascending or descending order. The last subscript in an array is the same as the number of variables in the array. Unless specified otherwise, scalar variables in C++ are passed by reference. Assigning initial values to an array is often referred to as populating the array.
