cout<<*(a+1);//2cout<<*(ptr-1);//5 数组名a本身就是指针,再加上个&就变成了双指针,这里的双指针就是指二维数组,&a+1,就是整体数组加一行,ptr指向a的第6个元素。 *A 可以看成一个(含有3个int元素的数组的)数组名,所以类推,去掉*,等于加上&, A是双指针,加1,就是数组整体加一行。
Below is the example to show all the concepts discussed above −Open Compiler #include <iostream> using namespace std; int main () { // an array with 5 elements. double balance[5] = {1000.0, 2.0, 3.4, 17.0, 50.0}; double *p; p = balance; // output each array element's value ...

You need to create a method that accepts a pointer to an array, searches that array for a particular element, and returns a pointer to the found element. Solution The FindInArray method, shown here, returns a pointer to an element found in an array: public unsafe int* FindInArray(int*...
arr1 is an array of 8 pointers to integers. int (*arr2)[8]; 1. arr2 is a pointer (the parenthesis block the right-left) to an array of 8 integers. int *(arr3[8]); 1. arr3 is an array of 8 pointers to integers.
First, create alib.pointerto an array of 99 points: BufferSize = 99; pBuffer = libpointer('int16Ptr',zeros(BufferSize,1)); Then, begin acquiring data and wait in a loop until it is done: calllib('myLib','AcquireData,BufferSize,pbuffer) ...
