How to get weekday?
I'm new in C and I want to know how to get the current weekday where sunday=0, monday=1,...,.
(using time.h if possible)
I want to do something like
Code:#include<stdio.h> #include<time.h> int main(void) { int week_day; if(week_day==0) //if sunday { do something; } }
Take a look here: <ctime> (time.h) - C++ Reference. You will probably be most interested in the time function and the gmtime or localtime functions (or their _r variants). For C, you will want to #include <time.h>. ctype is the C++ version of the header.
The integer value you want is in the tm_wday member of struct tm. Here is a snippet to demonstrate this:
See references for time and localtime for the detailsCode:time_t t = time(NULL); struct tm *now = localtime(&t); printf("%d\n", now->tm_wday);

Thanks! Just what I was looking for. Nice blog and youtube channel btw. Thanks again!!
