括号增加了它们内部操作的优先级。方括号执行数组索引。给定一个数组，方括号内的表达式提供了该数组的索引。 例如，

在C语言中，表达式通常从左到右进行评估计算的。这些运行符的优先级决定了评估的顺序。

成员描述tm_sec24小时制分钟后的秒数(0到60)。对于正闰秒支持，该值最高为60。

可以使用mktime()函数来确定给定日期的星期几。 该函数有原型：time_t mktime(struct tm *ptime);

#include stdio.h int main() //{ int x = 12; int y = 5; printf(\\nWithout Type-Casting\\n);

#include stdio.h int main(){ int x = 12; int y = 5; float result = 0; result = (float) x / (float) y;
