7.1 Assignment Operator

The assignment operator = assigns a value to a variable / object:

int main()

{

    char mychar = 'c';    // define a char variable mychar

    mychar = 'd';         // assign a new value to mychar

    int x = 123;          // define an integer variable x

    x = 456;              // assign a new value to x

    int y = 789;          // define a new integer variable y

    y = x;                // assing a value of x to it

}
