[https://mp.weixin.qq.com/s/ydhK8HYuRD0lZazPsPxsvg] c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///...

如果r 为tozero、negative 或positive,此标志将在程序开始执行时分别将舍入方向模式设置为舍入到零、舍入到负无穷大或舍入到正无穷大。当 r 为nearest 或未使用 -fround 标志时,舍入方向模式将保留其初始值不变(缺省为舍入到最接近的值)。 只有编译主程序时该选项才有效。 B.2.29 -fsimple[= n] 允许优化...
CArray::GetUpperBound Returns the largest valid index. CArray::InsertAt Inserts an element (or all the elements in another array) at a specified index. CArray::IsEmpty Determines whether the array is empty. CArray::RemoveAll Removes all the elements from this array. CArray::RemoveAt Removes...
Thelookupfunction has an obvious vulnerability to a buffer overflow since the parameter n is not checked for negative values before use as array index. Negative values can cause an out-of-bounds array index, expose restricted information, or allow modification of the contents of a restricted memor...
