Include Header File
The first step is to include the necessary header file using the #include
directive.
Using Namespace
By using the using namespace
directive, you can avoid having to qualify the names of the standard library methods and types with std::
.
Main Function
The main
function is the entry point of the program, where the program's execution begins.
Variable Declaration
In this step, you declare any variables that will be used in the program.
User Input
You can use input/output stream objects like std::cin
to get input from the user.
Perform Operations
Perform any calculations or operations using the variables and user input.
Display Output
Use the std::cout
object to display the output to the user.
#include <iostream>
using namespace std;
int main() {
// Variable declaration
int num1, num2, sum;
// User input
cout << "Enter first number: ";
cin >> num1;
cout << "Enter second number: ";
cin >> num2;
// Perform operations
sum = num1 + num2;
// Display output
cout << "Sum is: " << sum;
return 0;
}
