Can you use the name of an array as a pointer?

We use the array name as a pointer to store elements into the array. After that, we print the elements of the array using the same pointer. The compiler creates a pointer by default while we create an array.

Can you return a pointer to an array in C?

C programming does not allow to return an entire array as an argument to a function. However, you can return a pointer to an array by specifying the array’s name without an index.

Is the name of an array a pointer why is only the address of the first element of an array necessary to access the whole array?

When an array is used as a value, its name represents the address of the first element. When an array is not used as a value its name represents the whole array.

Is the name of an array a pointer in C?

An array is a pointer, and you can store that pointer into any pointer variable of the correct type. For example, int A[10]; int* p = A; p[0] = 0; makes variable p point to the first member of array A.

How do you return a pointer to an array?

Return Pointer to Array in C++

1. Use int var[n] Notation to Pass the Array Argument to Function and Then Return in C++
2. Use int* var Notation to Pass the Array Argument to Function and Then Return in C++
3. Related Article – C++ Array.

Which function returns the lower value of an array?

min() function
The min() function returns the lowest value in an array, or the lowest value of several specified values.

What is the relationship between array name and pointer?

Arrays and pointers are synonymous in terms of how they use to access memory. But, the important difference between them is that, a pointer variable can take different addresses as value whereas, in case of array it is fixed. In C , name of the array always points to the first element of an array.

What is array name in C?

Array name is a type of name or a type of any element name that is share by all elements of an array but its indexes are different. Array name handle as a constant pointer, it can never change during execution of a program. Array name is also used to reach its all element.

Is it possible to print an array in C++?

Most of the libraries commonly used in C++ can’t print arrays, per se. You’ll have to loop through it manually and print out each value. Printing arrays and dumping many different kinds of objects is a feature of higher level languages. It certainly is! You’ll have to loop through the array and print out each item individually.

Why can’t I print an array of random elements?

By only knowing a random element in an array (i.e. having a pointer to one element), you can’t print the entire array using that pointer. 1) Length of the array (which you seem to indicate always 10.)

Why can’t I cast pointers to (void*) in printf arguments?

It’s just a quirk of the language. Normally, it’s considered poor style to unnecessarily cast pointers to (void*). Here, however, you need the casts to (void*) on the printf arguments because printf is variadic. The prototype doesn’t tell the compiler what type to convert the pointers to at the call site.

How to check array access when bumping a pointer in C?

There is no bounds checking on array access when bumping a pointer in C, that’s up to you, as you will learn sooner or later from crashing programs. To get rid of confusion between pointers and referenced values you can read the instructive answers to “What exactly is a C pointer if not a memory address?”, here at Stackoverflow.
