To make full use of the C Programming language, you have to have a very good understanding of pointers. For most people it will take some time to fully understand pointers. So be patient. You have to learn pointers because they are used everywhere in the C language. Once you master the ...
Now, we can use pointers to point to the first character of an array of characters, and move through it. char*p2 ;//We use malloc to allocate 6 bytesp2 =malloc(6);printf("\n This is the address that pointer p2 is pointing at %d ", p2);//p2 is an address as well as a varia...
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 ...
Points to Remember while using Pointers A pointer variable stores the address of a variable. We use*to declare and identify a pointer. We can find the address of any variable using the&(ampersand) operator. The declarationint *adoesn't mean thatais going to contain an integer value. It me...
I assume you already know how to use pointers for strings. In addition to that, the most common uses for pointers are to: Walk through arrays Pass structures to functions Return multiple values from functions We'll look at each use in this article. Along the way, the article will show...

Thepointer to pointeris a useful concept in C programming language that allows you to indirectly access a variable value via multiple pointers layers. With the help ofpointer to pointer, you can manipulate a pointer by itself. The above-mentioned guidelines help you usepointer to pointerin C pr...

And sometimes you even have to use pointers, for example when working with files and memory management. But be careful; pointers must be handled with care, since it is possible to damage data stored in other memory addresses. Exercise? How do you declare a pointer to an int variable? int...
Arrays and pointers are intimately linked in C. To use arrays effectively, you have to know how to use pointers with them. Fully understanding the relationship between the two probably requires several days of study and experimentation, but it is well worth the effort. ...
