    Write a function called median that returns the median entry in a 1-dimensional array of integers. For example, if we have an array a={3,4,5,1,6}; then the median entry of this array a is 4. You need to sort the array a first, to get {1,3,4,5,6}, then find the entry in the middle position. If the array size is even, it means that array has even number of elements. For example, a={3,2,4,1}, then first sort it, a becomes {1,2,3,4}, then the...

    Write a value-returning C++ function returns the average length of an array of strings. Name the function stringsAverageLength and use the following header: double stringsAverageLength(string array [], int n) { } where the parameter 'array' has 'n' strings and the return value is the average length of all of the strings in the array. For example, if the function is called like this: string cars[3] = { "Toyota", "Ford", "Tesla" }; cout << fixed << setprecision(2) << stringsAverageLength(cars, 3) <<...

    1. Write code for a function that receives two parameters (a,and b) by value and two more parameters (c and d) by reference. All parameters are double. The function works by assigning c to (a/b) and assigning d to (a*b). The function has no return value. From main, use scanf to get two numbers, then call the function, and then display both outcome values to the output in a printf statement. 2. After part 1 is completed, write code to...
