C++ Program to Print Number Entered by User

C++ is one of the world’s most widely embraced programming languages. In this article, we will delve into some fundamental C++ programs ideal for newcomers to the language. Emerging in the early 1980s as an extension of the C programming language, C++ has garnered immense popularity for its versatility. It is extensively employed in crafting various applications, from system software, game development, and embedded systems to high-performance applications and beyond.

The strength of C++ lies in its ability to seamlessly blend high-level and low-level programming features, thereby striking an optimal equilibrium between performance and abstraction. Developers relish its support for procedural, object-oriented, and generic programming paradigms, which affords them the creative freedom to design and implement solutions as per their specific requirements.

#include <iostream>
using namespace std;

int main() 
{    
    int number;
    cout << "Enter an integer: ";
    cin >> number;
    Cout << nunber;
    return 0;

#include <iostream>
using namespace std;
int main() {
int a ;
cin>>a;
if(a%2 == 0)  // if remainder is zero then even number
    cout<<”even”;
else       
    cout<<”odd”;
return 0;
}
Input: 8

Output: even

#include <iostream>
using namespace std;
int main() {
int a = 10;
int b = 20;
cout<<a<<" "<<b<<endl;
int temp = a;
a = b;
b = temp;
cout<<a<<" "<<b<<endl;
return 0;
}

Output: 10 20
20 10

using namespace std;

        cout << num << " is Even.";

    else

        cout << num << " is Not Even ";
