WebBelow are the steps to create an array of pointers in c++, which are as follows; 1. First, we need to create an array that contains some elements. Let’s say 10 elements for now. Example: int myarray [2] = {100, 200}; 2. After this, we have to create an array of pointers that will store the address of the array elements. Example: int * myptr [2]; 3. WebJul 27, 2024 · If we dereference ( p+i) then we will get the base address of ith 1-D array but now the base type of * (p + i) is a pointer to int or ( int * ). Again to access the address of jth element ith 1-D array, we just have to add j to * (p + i). So * (p + i) + j points to the address of jth element of ith 1-D array. Web2 days ago · *p is a pointer to char[] (char *p=char int[1000]) When I output the char array later to see if the program is working, it doesn't work properly if the array was an empty array or a one-word array. Why does the array output random characters instead of blank space after I remove one word (when it is a one word array)? Example: Input: word family paderborn
