There are two different functions to get the absolute value of an integer



There are two different functions to get the absolute value of an integer

int abs(int) and of a double value double fabs(double):
cout << "The absolute value  of -10 is " << abs(-10) << endl;
cout << "The absolute value of 12.71 is " << fabs(12.71) << endl;
cout << "The absolute value  of -88 is " << abs(-88) << endl;
cout << "The absolute value  of 4 is " << abs(4) << endl;

Find Lowest Common Ancestor in Binary
This C++ program, using recursion, displays the "Lowest Common Ancestor" in a binary search tree. lowest common ancestor is one in which the lowest common parent node of

C++ Programming Subtract Two Matrices
Program ask to the user to enter any two 3*3 array elements to subtract them i.e., Matrix1 - Matrix2, then display the "subtracted" result of the two matrices ( Matrix3 ) on the screen:

C Language Program Infinite While Loops
C Code example of Infinite While Loop. Since the value of the variable var is same (there is no ++ or -- operator used on variable, inside the body of loop) the condition var<=2 will be

C++ Find Minimum Element Linear Search
First 'Compare the Element' at the beginning with another array element sequentially. And swap values if the element at the beginning is Larger than the other element. This value will

Program to calculate Average of array in C
This C program should give an insight of how to parse (read) array. We shall use a loop and Sum up all Values of the array. Then we shall divide the sum with the number of elements

C Program to Implement Stack Operations
C Implement stack operations using dynamic memory allocation. Use malloc function to allocate memory. Define separate functions for the operations like push, pop and display.

Implement Hash Tables Quadratic Probing
Returns whether n is "prime" or not. Find next prime size of the table. Function To Generate Hash. Function to Initialize Table. Function to "Find Element" at a key. Insert Element into a

Cryptography by Transposition Technique
This "C++" Program implement transposition technique. In "Cryptography", a transposition cipher is a method of encryption by which the positions held by units of plaintext (which are
