Here is the C++ program to find the sum of diagonals of a matrix. The matrix should be a square matrix. #include<iostream> using namespace std; int main() { int a[5][5],d1sum=0,d2sum=0,m,i,j; cout<<“Enter size of the square matrix(max 5):”; cin>>m; cout<<“\nEnter the Matrix row wise:\n”; for(i=0;i<m;i++) for(j=0;j<m;++j) cin>>a[i][j]; for(i=0;i<m;++i) for(j=0;j<m;++j) { if(i==j) d1sum+=a[i][j]; if(i+j==(m-1)) d2sum+=a[i][j]; } cout<<“\nSum …
In this article you will get program for bubble sort in C++. Bubble sort is a sorting technique in which each pair of adjacent elements are compared, if they are in wrong order we swap them. This algorithm is named as bubble sort because, same as like bubbles the smaller or lighter elements comes up …
This is a C++ program to delete an element from array. The user input an element to delete, the element is then searched in the array, if it is found it is deleted and new array is displayed. If the element is not present in the array then a not found message is displayed. #include<iostream> …

Here you will get program for linear search in C++. In linear search algorithm, we compare targeted element with each element of the array. If the element is found then its position is displayed. The worst case time complexity for linear search is O(n). Program for Linear Search in C++ #include<iostream> using namespace std; int main() …
Actually this program doesn’t creates a facebook login screen. I have just used graphics to create two boxes with an option to enter username and password. This is program is to just give you an idea that how you can create a login screen for your project. #include<conio.h> #include<iostream.h> #include<graphics.h> #include<stdio.h> #include<dos.h> #include<process.h> void logo() …
