C++ Assignment Operators

In C++, assignment operators allow variables to store and update values efficiently. These operators assign values directly or perform operations before assignment.

Basic Assignment (=)

The simplest assignment operator is =, which stores a value in a variable.

Example

#include <iostream>
using namespace std;

int main() {
    int engineCC = 1000;  // Assigning a value
    cout << "Engine capacity: " << engineCC << " cc";

    return 0;
}

#include <iostream>

using namespace std;

​

int main() {

    int engineCC = 1000;  // Assigning a value

    cout << "Engine capacity: " << engineCC << " cc";

​

    return 0;

}

​

Using Compound Assignment Operators

Assignment operators can modify variables while assigning a value.

Example

#include <iostream>
using namespace std;

int main() {
    int torque = 80;  // Initial value

    torque += 20;  // Adds 20 to torque (80 + 20 = 100)
    
    cout << "Updated torque: " << torque << " Nm";

    return 0;
}

#include <iostream>

using namespace std;

​

int main() {

    int torque = 80;  // Initial value

​

    torque += 20;  // Adds 20 to torque (80 + 20 = 100)

    cout << "Updated torque: " << torque << " Nm";

​

    return 0;

}

​

This shorthand makes the code cleaner, eliminating the need for torque = torque + 20;.
