Note: To get the value of ptr, which is actually the address of a, we can use *dptr.I hope this post will be helpful to understand the concept of pointers in C++. Here, I just wrote simple examples of pointers in C++. If you want to practice more examples on pointers, visit: C ...
const data_type constant_name = value; Read: constant declaration in C/C++In this program, we are declaring 4 constants:String constant (character array constants): MY_NAME and MY_ADDRESS Integer constant: MY_AGE Float constant: MY_WEIGHTC++ code to declare and print the different constants...
We already know, when we initialize a normalarray(or you can say one dimensional array) during declaration, we need not to specify the size of it. However that’s not the case with 2D array, you must always specify the second dimension even if you are specifying elements during the declar...
In C and C++ programming, pointers are very powerful. As we explained inC pointers examplearticle, pointers are variables that hold address of another variable so that we can do various operations on that variable. Sometimes a programmer can’t imagine writing a code without using pointers, wheth...

There's a bit more to it, though, have a look at Why C Pointers by Andrew Hardwick, that's a good read. How does that save memory? A pointer is a reference (the address) to data in memory. This data could be an instance of a person class, for example. This person object takes...
Levels of difficulty: medium / perform operation: Array, Pointer Program #include <stdio.h> int main(void) { char multiple[] = "My string"; char *p = &multiple[0]; printf("\nThe address of the first array element : %p", p); p = multiple; printf("\nThe address obtained from ...

In this tutorial, you will learn how to pass a pointer to a function as an argument. To understand this concept you must have a basic idea of Pointers and functions in C programming. Just like any other argument, pointers can also be passed to a function
