What will be the output of the following C++ code? #include <iostr...
Explanation:
Main Function:
- In the main function, a variable of type Time named 't' is created and initialized with hours = 5, minutes = 30, and seconds = 45.
- The function toSeconds(t) is called and its return value is printed, which calculates the total seconds from the Time structure.
toSeconds Function:
- The toSeconds function takes a Time structure as a parameter and calculates the total number of seconds.
- It multiplies the hours by 3600 (number of seconds in an hour), the minutes by 60 (number of seconds in a minute), and adds the seconds to get the total seconds.
Calculation:
- Total seconds = 3600 * 5 + 60 * 30 + 45
- Total seconds = 18000 + 1800 + 45
- Total seconds = 19845
Therefore, the output of the code will be:
Total seconds: 19845

- Total seconds = 18000 + 1800 + 45
- Total seconds = 19845
Therefore, the output of the code will be:
Total seconds: 19845
