In this article, we will see how you can Count the days between two dates in C++. Code: In this code, the countLeapYears() function will check whether the given date is a leap year or not by checking the year is a multiple of 4 multiple of 400 and not a multiple of 100. and the getDifference() function returns …
In this tutorial, we will rotate an Image at 45, 90 & 180 degrees using OpenCV in C++. Opencv is a library that contains multiple computer-vision libraries, used for real-time computer vision. Requirements: OpenCV To get started you need to install OpenCV in your system. You can follow the OpenCV documentation to install it into …
#include <opencv2/opencv.hpp> using namespace cv; int main() { // Read the color image Mat colorImage = imread(“input_color_image.jpg”, IMREAD_COLOR); // Convert the color image to grayscale Mat grayImage; cvtColor(colorImage, grayImage, COLOR_BGR2GRAY); // Save the grayscale image imwrite(“output_gray_image.jpg”, grayImage); return 0; } 1 ) In these code we explain about the this line includes the …

Here, we discuss how we find the last element of an array using C++. CODE #include<iostream> using namespace std; int main(){ int arr[]={5,6,7,8,9} int size = sizeof(arr) / sizeof(arr[0]); int lastElement = arr[size – 1]; cout<<“The last element of the array is: “<<lastElement<<endl; return 0; } OUTPUT The last element of the array is: 9 …

In this tutorial, we will learn how to detect operating systems using C++. Detecting operating systems is a common requirement when you develop a cross-platform project that’s why today we learn how to detect the operating system using C++. Detect Operating system using C++ #include <iostream> #if defined(_WIN32) const std::string OS = “Windows”; #elif defined(__APPLE__) …
In this tutorial, we will learn how to rename a file using C++. Renaming the file is a very important thing if we save any file name by mistake in that time we need to rename our file name that’s why renaming is a very important thing. Rename a file using C++ #include <iostream> #include …
In this tutorial, we will learn how to remove null values from an Array in C++. It is important to remove the null value for Memory Optimization,Efficient Data Processing, and Data Integrity purposes. Removing null values from arrays is a common task in C++ programming, especially in data processing and algorithm development Approaches to remove …
what is iswlower ()? iswlower() is a function provided by the C and C++ standard libraries for working with wide characters (wchar_t), which are capable of representing a broader range of characters than the regular char type. Specifically, iswlower() is used to determine whether a wide character is a lowercase letter. #include <cwctype> int iswlower(wint_t …
This tutorial will teach us how files and folders are listed in a specific directory. And we are going to complete this process using C++ Programming Language. C++ Implementation #include <sys\stat.h> #include <iostream> #include <dirent.h> #include <conio.h> using namespace std; int main () { struct dirent *d; struct stat dst; DIR *dr; string path = …
