int a[]={1,2};合法, int a[][3]={2,3,4};合法, int a[2][]={2,3,4};非法。 数组初始化元素值默认为0,没有初始化元素值为随机。如在int a[5]={0,1,2};中,元素a[4]值为0;而在int a[5];中,元素a[4]值为一个不确定的随机数。 【考点3】元素的引用 数组元素的下标从0开始,到...

解析 B 正确答案:B解析:在C语言中,用户标识符不能是C语言的合法关键字,同时规定命名只能是字母(A~Z,a~z)、数字(0~9)、下画线(_)组成的字符串,并且其第一个字符必须是字母或下画线。int是C语言的合法关键字,AD不满足命名规则。故只有B是正确的。 知识模块:C语言...
int main() { std::thread t(do_some_work); t.join(); } std::thread 在<thread>头文件中声明,因此使用 std::thread 时需要包含<thread>头文件。 每个线程都必须具有一个入口函数,当线程执行完入口函数后,线程也会退出 main线程叫做主线程(每个线程都一定会有一个主线程,只有主线程的叫做单线程程序),...
