The C++ Booth's Multiplication Algorithm -
"Multiply two Signed numbers" using Booth's algorithm. Booth's multiplication algorithm is a multiplication algorithm that multiplies two signed 'binary numbers' in two's complement
Generate All Possible Subsets With Exactly -
Algorithm takes the input of "n" data element and 'prints all possible' combination of length 'k'. It maintains a boolean array of length 'n'. If the corresponding boolean value is true, then
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
Checking Whether Number is Even or Odd -
In this example, if...else statement is used to check whether a number entered by the user is "even or odd". Integers which are perfectly "divisible by 2" are called even numbers. And
Program Code Demonstrate Nested Printf -
Print to 'abcdefghijklmnopqrstuvwxyz' while executing inner printf. Length of the "abcdfg hijklmnopqrstuvwxyz" is 26. Printf will return Length of String. It returns 26 to outer printf
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
Code print the address of array elements -
For loop to print value and address of each element of array. Just to demonstrate that the array elements are stored in contiguous locations, I am displaying the addresses in...
