Function strftime () in C

The syntax of the function is as follows:

size_t strftime(char* s, size_t maxsize, const char* format, const struct tm * Tmptr);

The function strftime () formats the broken-down time tm into an array pointed to by s according to the specified formatting string pointed to by format. The size of array is limited by maxsize. The formatting string consists of 0 or more conversion Specifiers and ordinary characters. The ordinary characters placed in the formatting string are copied into s without any conversion. Each specifier consists of a percent character(%) followed by a character that determines the action of conversion specifier. Some conversion Specifiers may have an additional modifier character E or 0 placed between% symbol and the conversion specifier character. The strftime() function returns the number of characters placed in the arrays, not including the terminating Null character.
