Program to implement Specify command

Count Numbers of Words Digits & Vowels - Program find number of words, blank spaces, Special symbols, Digits, "Vowels" by pointers. We are going to accept string use 'gets()'. We are not using scanf() to accept string because

Calculate Display the Grade of the Student - To calculate "grade of a student" on the basis of his total marks in C++ Programming, ask to the user to enter marks obtained in some subjects (5 subjects here). To calculate grade

C++ Compute Combinations by Factorials - Prints a total number of combination possible for given n and r value. The "time complexity" of this algorithm is O(n). This algorithm takes the input of n and r value. Function to find the

Implement Find all Cross Edges in a Graph - This C++ program, "using recursion", displays the number of cross edges in a graph. A cross edge is one in which a node points to another node which has already been fully visited. Int

C++ Generating All Subsets of a Given Set - Program print all the possible combination of each length from the given array in gray code order. The 'time complexity' of this algorithm is 'O(n*(2^n))'. This algorithm takes the input

Code Illustrate Reading of Data from Files - Program to illustrates reading of data from a file. Program to opens a file which is present. Once the file opens successfully, it uses libc fgetc() library call to read the content. Code

C++ Codings Quick Sort & Randomization - Quick sort is based on an 'algorithmic' design pattern called 'divide-conquer'. Unlike Merge Sort it does not require 'extra memory space'. The average time complexity is "O(n*log(n))"

C++ Simple Calculator Code for Beginners - Write a simple C++ program which have four different functions for "basic operations" like addition, subtraction, division, multiplication. It should be menu based asking user to enter
