wages[1] Pk *(wages + 1);arrayName[i] becomes *(arrayName + i); pointerName[i] becomes *(pointerName + i) 数组名,指针名 都可以表示数组地址,但指针名值可改变,数组名值及所代表的地址值不可变更,--数组名 常量; pointerName = pointerName + 1执行下一个数组的元
如int *p; 去掉一个 * 和变量名 p 后就只有 int 了,所以 p 指向 int 的整形数。 float **p; 则 p 指向的类型是 float *,即 float 类型的指针,或 float 类型的地址,也即数组。 那么在给 p 分配内存时,p = new float*[23],即指向一些 在C或C++中有一个很好的地方是,即使你定义的变量是指针,但...

PointerIn C language, it is difficult to use the pointer to access the two-dimensional array element. The reason is the addresses of two-dimensional array are many, pointers that can access the two-dimensional array element are many and complex. This paper analyzes the two-dimensional array ...
Summary: In this programming tutorial, we will learn different ways to convert a number of type int into a char pointer or array in C++. Method 1: Using to_string() and c_str() In this method, we first convert the given number into a c++-string and then transform it into the ...
