### C program to convert lowercase string to uppercase

Get Highest Frequency Character in String -
C Program finds 'highest frequency' character in a string. C Program checks which character has 'occured more number' of times & checks how many times these character has occured

Quick Sort with the Complexity Constraint -
Randomly select pivot value from the subpart of the array. Partition that subpart so that the values left of the 'pivot' are smaller and to the right are greater from the pivot. And consider

Finds Independent Sets in Graph by Graph -
Code finds 'largest independent' set by graph coloring. In graph theory, an independent set or stable set is a set of vertices in a graph, no two of which are adjacent. That is, it is a set I

The C++ Shortest path program using STL -
Process a request; return false if end of file. A simple main that reads a file given by argv[1] and then calls "processRequest" to compute shortest paths. Then 'Skimpy' error checking

Implementations Quadratic Probing Hashs -
Internal method to test if a positive number is prime. Not efficient algorithm. Using Internal method to return a prime number at least as large as n. Assumes "n > 0". Insert item x into

Count the Numbers of Vowels Consonants -
This program takes string input from the user Stores in variable line. Initially, the 'Variables' 'vowels', 'consonants', 'digits' and 'spaces' are initialized to 0. When the "vowel character" is

Binary Search Algorithm in C++ Language -
A program which takes some 'Elements' in an array and a 'Key' in variable then program use 'Binary Search' C++ Algorithm to find the key. One to sort array using 'Bubble Sort'. Second

Program Sortings an Array of 10 Elements -
"Heapsort" can be thought of as an improved "selection sort": like that algorithm, it divides its input into a sorted and an unsorted region, and it iteratively shrinks the unsorted region
