Let’s see examples of operator overloading in C++ for various types of operators. Examples: 1) Add given timestamps by overloading + operator setTime() function is used to set HR, MIN and SEC values. showTime() function displays the time in a specific format (HH:MM:SS). We add the seconds, minutes, and hours separately to get the new time […]
