### C++ Program to Implement Merge Sort

C++ Implementations Binary Search Tree -
Insert x into the tree; duplicates are ignored. Remove x from the tree. Nothing is done if x is not found. Find the "smallest item" in the tree. Find the "largest item" in the tree. Find

Program to Store Information of Students -
In this c program code, a structure, student is created. This structure has three members: name (string), roll (integer) and marks (float). Then, we created a structure array of size 10

Check Prime or Armstrong Number Using -
In this program, two User-Defined functions checkPrimeNum() & checkArmstrongNum() are created. The checkPrimeNum() returns 1 if the number entered by the user is a Prime

Find sum of Even Numbers in given Range -
Input upper limit to find sum of even number. Store it in a variable say N. Initialize another variable to store sum with 0 say sum = 0. To find sum of even numbers we need to iterate

Computes DFT Discrete Fourier Transform -
C++ Program to compute the 'coefficients' of the DFT (Discrete Fourier Transform) directly. In math, the discrete Fourier transform (DFT) converts finite list of equally spaced samples

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

Code Parse the Command Line Arguments -
C program is an example of how to parse the command line arguments. It sets up all the global variables for a real program and it just doesn't have any body. Loop for each option.

Trim Leading & Trailing white spaces from -
I already explained how to remove leading as well as trailing white space characters from a given string. In this program we will Combine the logic of both in a single program. Logic to
