In this section we will see how to see the Host name and IP address of the local system in an easier way. We will write a C program to find the host name and IP.Some of the following functions are used. These functions have different task. Let us see ... Read More

This is a C++ Program to Implement Gauss Jordan Elimination. It is used to analyze linear system of simultaneous equations. It is mainly focused on reducing the system of equations to a diagonal matrix form by row operations such that the solution is obtained directly.AlgorithmBegin    n = size of ... Read More

In C++ we can omit the curly braces after if-else statements, or after any loop. If we do not use curly braces then only one statement after the if-else or loop will be considered under that block. For example −if(condition) {    Line 1    Line 2 } if(condition) ... Read More

This is a C++ program to apply Above-Below-on Test to find the position of a point with respect to a Line. For any point t (xt, yt) on the plane, its position with respect to the line L connecting m and n is found by calculating the scalar s −Y ... Read More

We shall develop a C++ program to implement Gift Wrapping Algorithm in two dimensions. The Gift Wrapping Algorithm is an algorithm for computing the convex hull of a given set of points.AlgorithmBegin    function convexHull() to find convex hull of a set of n points:    There must be at ...

This is a C++ Program to Find Minimum Value of any Algebraic Expression.An algebraic expression of the form (x1 + x2 + x3 + . . . + xa) * (y1 + y2 + . . . + yb) and (a + b) integers is given.consider all possible combinations of ... Read More

In this section, we will see how to get the current working directory using C or C++. We have defined some flags for the current operating system.Example Code Live Demo#ifdef WINDOWS #include #define GetCurrentDir _getcwd #else #include #define GetCurrentDir getcwd #endif #include using namespace std; std::string get_current_dir() ...
