Modify the selection sort function developed in this chapter so that it accepts a second optional argument, which may be either 'up' or 'down'. If the argu-ment is 'up', sort the data in ascending order. If the argument is 'down', sort the data in descending order. If the argument is missing, the default case is to sort the data in ascending order. (Be sure to handle the case of invalid arguments, and be sure to include the proper help information in your function.) Here is the given function which need to be mofified: function out = ssort(a) nvals = length(a); iptr = ii; for jj = ii+1:nvals if a(jj) < a(iptr) iptr = jj; end end if ii ~= iptr temp = a(ii); a(ii) = a(iptr); a(iptr) = temp; end end out = a;

Each function deals with null terminated C-strings. You can assume that any char array passed into the functions will contain valid, null-terminated data. Your functions must have the signatures listed below. This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2. It should return -1 if the substring does not appear in the string. int findSubstring(char *s, char substring[])
PHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .

Complete the below code with function declaration which is void sort and argument array you required to use qsort function with standard library.. Please so as soon as
If you pass a variable by function's execution. Changes to the parameter are not made to the argument. to a function, the function will make a local copy of that variable and use that copy throughout the Array indexing always starts with the number: Declare an array called grades that can hold 100 integers.
It's important to note that the name of an array by itself is really a pointer to the first element of the array. Therefore passing an array to function is simple since you can just specify the name of the array. Are these statements true?
use C++ programming language Write a modular program that analyzes a year’s worth of rainfall data. In addition to main, the program should have a getData function that accepts the total rainfall for each of 12 months from the user and stores it in an array holding double numbers. It should also have four value-returning functions that compute and return to main the totalRainfall, averageRainfall, driestMonth, and wettestMonth. These last two functions return the number of the month with the lowest and highest rainfall amounts, not the amount of rain that fell those months. Notice that this month number can be used to obtain the amount of rain that fell those months. This information should be used either by main or by a displayReport function called by main to print a summary rainfall report similar to the following: 2019 Rain Report for Springdale County Total rainfall: 23.19 inches Average monthly rainfall: 1.93 inches The least rain fell in January with 0.24 inches. The most rain…
