You can find out how many seconds have elapsed since Jan 1, 1970 using the time() function. #include now = time (NULL); // now is more than a billion seconds (which data type should you use?) Write a program that estimates how many years, months, weeks, days, and hours have gone by since Jan 1 1970 by calculations with the number of seconds that have passed. The number of months must be less than 12, i.e., take out how many years have gone by first, then how many months are left, then weeks, etc. Assume that all years have 365 days, and all months have 30.42 days. Don't use a calculator, or any web site that reports the number of seconds in a month, etc. – your C program can calculate anything that you need. Notice that this is an assignment on using arithmetic in C. Hints. How many seconds are in a minute? hour? A day? A week? A month? A year?
I attached instructions for a simple C program. May you please copy and paste the code for me?
Algorithm Steps:-
1. Find the number of seconds since Jan 1, 1970, using the time(NULL) function call and store the returned value in a Long Long variable.
2. Calculate and store the constant number of seconds in a year, month, week, day, and hour. For example number of seconds in an hour = 60*60, the number of seconds in a day = 60*60*24, and so on.
3. Starting from the biggest unit i.e. year- calculate the number of years passed by dividing the total number of seconds by the number of seconds in a year calculated in step 2.
4. Calculate the number of seconds left by finding the modulus (remainder) of total seconds with a number of seconds in a year.
5. Repeat steps 3 and 4 for all smaller units - months, weeks, days, and hours.
6. Display the calculated results as a well-formatted string.
