C语言基础：mktime用法演示，输出时间差的代码

将代码过程中比较重要的一些代码片段记录起来，如下的代码内容是关于C语言基础：mktime用法演示，输出时间差的代码。

#include
#include

int main(void)
{
time_t seconds;

struct tm time_fields;

time_fields.tm_mday = 4;
time_fields.tm_mon = 7;
time_fields.tm_year = 94;
time_fields.tm_hour = 0;
time_fields.tm_min = 0;
time_fields.tm_sec = 0;

seconds = mktime(&time_fields);

printf(“The number of seconds between 7-4-94 and 1-1-70 is %ldn”,
seconds);

return 1;
}

输出结果：GCC编译

The number of seconds between 7-4-94 and 1-1-70 is 775929600
