C++ Statements

In programming, a statement represents a single instruction that a computer follows to perform a task. A C++ program consists of multiple statements that guide the execution of operations in a structured manner.

Writing a Statement in C++

A simple statement instructs the compiler to display text on the screen:

cout << "Rev up your engines!";

cout << "Rev up your engines!";

​

Each statement must end with a semicolon (;). If omitted, the compiler will generate an error:

Example (Incorrect):

cout << "Rev up your engines!"

cout << "Rev up your engines!"

​

Error: expected ';' before 'return'

Executing Multiple Statements

Most C++ programs contain several statements that execute sequentially—meaning each statement runs in order from top to bottom.

Example:

#include <iostream>
using namespace std;

int main() {
    cout << "Rev up your engines!" << endl;
    cout << "Time to hit the road!" << endl;

    return 0;
}

#include <iostream>

using namespace std;

​

int main() {

    cout << "Rev up your engines!" << endl;

    cout << "Time to hit the road!" << endl;

​

    return 0;

}

How It Works:

In the example above, three instructions are executed one by one:

1. The first statement prints "Rev up your engines!" on the screen.
2. The second statement outputs "Time to hit the road!".
3. The third statement (return 0;) signals that the program has successfully completed execution.
