c/c++ 中经常会遇到时间和字符串互相转化的情形

用以下2个函数来转就很方便了

1、时间转字符串函数

size_t strftime(char *strDest, size_t maxsize, const char *format, const struct tm *timeptr);

2、字符串转时间函数

char *strptime(const char *s, const char *format,struct tm *tm);

#include <stdio.h>  
#include <time.h>  
 
int main(int argc, char *argv[]) {  
    struct tm tm_time;  
    strptime("2010-11-15 10:39:30", "%Y-%m-%d %H:%M:%S", &tm_time);  
    printf("%ld/n", mktime(&tm_time));  
    printf("-------------------------------------/n");  
  
    char szBuf[256] = {0};  
    time_t timer = time(NULL);  
    strftime(szBuf, sizeof(szBuf), "%Y-%m-%d %H:%M:%S", localtime(&timer));  
    printf("%s/n", szBuf);  
  
    return 0;
