The correct answer is: B. pointer to<\/strong><\/p>\n An asterisk placed after a data type means that the variable is a pointer to that data type. A pointer is a variable that stores the address of another variable. This allows you to access the value of the other variable indirectly, through the pointer.<\/p>\n For example, if you have a variable called The variable This will set the value of You can also use pointers to create arrays. For example, if you want to create an array of 10 integers, you can do so as follows:<\/p>\n However, if you want to create a pointer to an array of 10 integers, you can do so as follows:<\/p>\n The variable This will set the first three elements of the array to 10, 20, and 30, respectively.<\/p>\n Pointers are a powerful tool that can be used to manipulate data in a variety of ways. However, they can also be dangerous if not used properly. It is important to understand the concept of pointers before using them in your code.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”array to” option2=”pointer to” option3=”address to” option4=”located to” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[683],"tags":[],"class_list":["post-50963","post","type-post","status-publish","format-standard","hentry","category-object-oriented-programming-using-c-plus-plus","no-featured-image-padding"],"yoast_head":"\nx<\/code> that is of type int<\/code>, you can declare a pointer to int<\/code> called p<\/code> as follows:<\/p>\nint x;
