Solution for Exercise 21-2

ex2102

#include <stdio.h>
#include <time.h>

int main()
{
    time_t tictoc;

    tictoc=time(NULL);
    printf("The time is now %ld\n",tictoc);
    return(0);
}

Output

The time is now 1589835271

Notes

* You have your choice of how to eat the value generated by time(). The function requires a pointer, so if you'd rather just take the time_t value returned, stick a NULL between the parentheses. Otherwise, you can specify the address of a time_t value. Don't let this flexibility confuse you.
