How do you return a string 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.

How do you return an array of strings?

In the following example, the method returns an array of integer type.

1. import java.util.Arrays;
2. public class ReturnArrayExample1.
3. {
4. public static void main(String args[])
5. {
6. int[] a=numbers(); //obtain the array.
7. for (int i = 0; i < a.length; i++) //for loop to print the array.
8. System.out.print( a[i]+ » «);

Can you return a string in C?

Strings in C are arrays of char elements, so we can’t really return a string — we must return a pointer to the first element of the string. … Note that you can’t modify a string literal in C.

Can you return a char array in C?

If you want to return a char array from a function, you should declare the function as returning char* not char. But you seem intent on returning the contents of a char array, rather than the pointer that the C language pretends is the same type as the array.

How is a string stored in an array in C?

String literals are stored in C as an array of chars, terminted by a null byte. A null byte is a char having a value of exactly zero, noted as ‘’. Do not confuse the null byte, ‘’, with the character ‘0’, the integer 0, the double 0.0, or the pointer NULL.

How does an array work?

An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. … Each item in an array is called an element, and each element is accessed by its numerical index.

When an array is passed to a method?

You can pass arrays to a method just like normal variables. When we pass an array to a method as an argument, actually the address of the array in the memory is passed (reference).

How do I return a string?

In order to do what you’re trying to do, you need to do one of the following:

1. Allocate memory on the heap using malloc or similar, then return that pointer. …
2. Allocate the string on the stack in the calling function (the one that will be using the string), and pass a pointer in to the function to put the string into.

How do I return a char pointer?

Or instead of char file[30]; do a dynamic memory allocation : char* file = malloc(30); then you can do return f; and it will work fine because f now is not a pointer to a local variable. What you’re doing is returning a pointer to a local variable, which used to be allocated on stack.

What is Strcpy C?

The strcpy() Function in C

The strcpy() function is used to copy strings. It copies string pointed to by source into the destination . This function accepts two arguments of type pointer to char or array of characters and returns a pointer to the first string i.e destination .

How do I return a char array?

If you want to return a char* from a function, make sure you malloc() it. Stack initialized character arrays make no sense in returning, as accessing them after returning from that function is undefined behavior. char* charP = createStr(); Would be correct if your function was correct.

What is the difference between char pointer and char array?

Originally Answered: What’s the difference between char* and char [] in C++? One is a pointer, and the other is an array. Pointers and arrays are fundamentally different: an array is a sequence of contiguous objects, and a pointer is an object that holds the address of another object.

How do I return a pointer array?

Returning pointer pointing to the array

1. #include <stdio.h>
2. int *getarray()
3. {
4. int arr[5];
5. printf(«Enter the elements in an array : «);
6. for(int i=0;i<5;i++)
7. {
8. scanf(«%d», &arr[i]);

Can we store string in array?

Arrays can contain any type of element value (primitive types or objects), but you can’t store different types in a single array. You can have an array of integers or an array of strings or an array of arrays, but you can’t have an array that contains, for example, both strings and integers. … Store things in that array.

What string means?

A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers. For example, the word «hamburger» and the phrase «I ate 3 hamburgers» are both strings.

What are the types of arrays?

There are three different kinds of arrays: indexed arrays, multidimensional arrays, and associative arrays.

• Creating Indexed Arrays. Indexed arrays store a series of one or more values. …
• Creating Multidimensional Arrays. …
• Creating Associative Arrays.
