In this tutorial, we would learn to write a program in C++ to check whether a number is even or odd. #include <iostream> using namespace std; int main() {     int n;     cout<<"Enter an integer : ";     cin>>n;     if(n % 2 == 0)     {         cout<<n<<" is even.";     }     else     {         cout << n << " is odd.";     }     return 0; } Tutorial HTML tutorial CSS tutorial JavaScript Tutorial Web de ..read more

In this tutorial, we would learn to write a program in C++ to find the largest or smallest number of 3 different numbers. #include<iostream> using namespace std; int main() {     //declaration of variables     int num1, num2, num3;     int smallest, largest;     //take input from user     cout << "Please enter 3 numbers : "<<"" ;     cin >> num1 >> num2 >> num3;     //assign initial value for comparison     smallest = num1;     largest = num1;     if ..read more

In this tutorial, we would learn to add numbers together. Imagine when you have up to 30 numbers you want to add. • The first thing you need is speed. How fast can you add 30 numbers • Second is accuracy. How accurate will your answer be when you add them. How do you avoid mistakes. That is the major reason why you need to write a program. Here is the code in C++ #include<iostream> using namespace std; int main() {     int times, num, sum,i;     times=num=sum=i=0;     cout << "Input the number of integers you want to add:";     cin ..read more

In this tutorial, we would learn to swap two numbers and write a program in C++ . Swapping two numbers manually is one of the easiest thing to do but imagine you writing a program that will do this very fast. #include<iostream> using namespace std; int main() { int num1, num2, swap;  cout<<"Enter first number:  ";  cin>>num1;  cout<<"Enter second number:  ";  cin>>num2;  cout<<"\nValues Before swapping:  \n"<<endl;  cout<<"First Integer ="<<num1<<endl;  cout<<"Seco ..read more

In this tutorial,we would learn to write a program in C++ to reverse numbers. #include <iostream> using namespace std; int main() { int number, reverse = 0; cout<<"Input a Number to Reverse "; cin>> number;    while(number!= 0)    {       reverse = reverse * 10;       reverse = reverse + number%10;       number = number/10;    }    cout<<"New Reversed Number is:  "<<reverse;    return 0; } Tutorial HTML tutorial CSS tutorial JavaScript Tutorial Web devel ..read more

In this tutorial, we would learn to write C++ program to find the factorial of any number. The program will ask user to enter number then the program will find the factorial and then print the factorial of the number. Here is the code. #include<iostream> using namespace std; int main() {     int num,factorial=1;     cout<<"Enter number  ";     cin>>num;     for(int a=1;a<=num;a++)     {         factorial=factorial*a;     }          cout<<"Facto ..read more

In this tutorial , we would learn to write a code in C++ to check whether a particular number we enter is a palindrome. #include<iostream> using namespace std; int main() {     int i,temp,d,revrs=0;     cout<<"Enter the number : ";         cin>>i;     temp=i;     while(temp>0)     {         d=temp%10;         temp/=10;         revrs=revrs*10+d;     }     if(revrs==i)         cout<<i<<" i ..read more
