C++ Sample Code Make Simple Calculator -
To make a simple calculator in the C++, which performs basic four mathematical operations (addition, subtraction, multiplicatin, division) depending on the "user's choice", switch case

C++ Describe the Representation of graph -
Takes the input of the 'number of vertex'. For each pair of vertex ask user whether they are connected or not. Print the adjacency matrix. A function to print the adjacency matrix. And

C++ Finds the Minimum Element of Array -
Construct binary search tree for the unsorted data array. For the "minimum element" move the pointer to the leftmost child node. So the value will be the "minimum value" among the

C++ Implement Shortest Path Algorithm -
For a general weighted graph, we calculate single source shortest distances in "O(VE)" time using 'Bellman-Ford Algorithm'. For a graph with no negative weights, we can do

C++ Shutdown & Restart Your Computer -
C++ sample made for both i.e., to shutdown your computer or to 'restart your computer', first it will ask to the user want to shutdown computer or want to restart computer. Then

C Code Accept an Array & Swap Elements -
C Program accepts array and swap elements using pointers. C program to accept an array of 10 elements and swap 3rd element with 4th element using pointers and display the

Writing Data into a Text File C++ program -
A 'while loop' is used and will terminate when user will press esc key. To get the characters a function 'getche()' is used from conio.h which will store in 'char variable' & store into the file

C Code Selection Sort Method by Function -
C Program implements selection sort method using functions. 'Selection' Sort is among the simplest of Sorting Techniques. Lets first find the smallest in the array and exchange it with
