Solution for Exercise 21-7

ex2107

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

int main()
{
    time_t tictoc;
    struct tm *today;

    time(&tictoc);
    today = localtime(&tictoc);
    printf("Today is %d/%d/%d\n",
        today->tm_mon+1,
        today->tm_mday,
        today->tm_year+1900);
    return(0);
}

Notes

* The localtime() function stuffs the tm structure with values representing the current time — except for the month and year. The month value starts with 0 for January, so the tm_mon member must be incremented by one. The year is measured from 1900. Therefore, in Line 14, the tm_year member must be adjusted.
