Write a c program for selection sort using functions in word

When you need to refer to the sorted array, you can call upon this "tagged" array that holds the correct ordering of when the array is sorted. Prompt for and get the input file name and try to open the file. You either use the qsort function provided by the standard library, or you use your own function e.

Here is an example: Display the names in the array before sorting unsorted list Display the names in the array after sorting sorted list Save the sorted array to a data file Processing Requirements Define all functions after main function and prototype them properly.

Insertion Sort Insertion sort does exactly what you would expect: Here is the code for a simple selection sort: The user must enter the number of names to process and names of the input file and output file. Then the process is repeated for the remainder of the array; the next largest element is selected and put into the next slot, and so on down the line.

If the file is not found, do NOT process the names. Above, in the first example, when we approached using qsort, we had to answer the question: String Selection Sort Concepts tested by the program: In C, the standard string comparison function is strcmp or strncmp to limit the number of characters compared.

However, there may be times when you would like to sort an array without having to directly change the elements in the array. For example, consider the following integer array and integer tag array: Read on for more After the tag sort for ascending order is executed and completed, the arrays would contain the following elements: Read the names from the data file: In other words, the actual elements are not being changed during the sort process, rather the positions in the tag array are being changed so they will hold the correct ordering of the sorted elements of the array.

Display the unsorted array. It works by selecting the smallest or largest, if you want to sort from big to small element of the array and placing it at the head of the array.

We need to sort strings, so the compare function must provide a way of comparing strings. When using qsort your only task is to write a compare function to pass to the qsort function that tells qsort how to sort your data.

Assume that the data file contains 20 names on separate lines and is constructed correctly. Basically, changing only the compare function and the inputyou can then use qsort to sort your array of strings, as follows: Try to devise a solution to this problem before reading on to see how I came up with a solution.

Selection sort Selection sort is the most conceptually simple of all the sorting algorithms. Because a selection sort looks at progressively smaller parts of the array each time as it knows to ignore the front of the array because it is already in ordera selection sort is slightly faster than bubble sort, and can be better than a modified bubble sort.

Note that the function will also use a "swap" function so the values can be manipulated during the sort process: The program will 1 read the names from a string data file and place them in an array, and 2 sort the names in the array in ascending order using selection sort.

The following is a tag sort function that can be used to sort an array of integers into ascending order. Therefore, all your compare function needs to do is return whether of the two characters: The program should have the follow output: The string array should be a parameter.
