In char[] you are assigning it to an array which is not a variable..

What is the difference between char * and char []?

Char* is a pointer reference whereas char[] is a character array. Char* points to memory location where the contents are stored. Char[] is a structure , it’s a specific section of memory which allows things like indexing, but always starts at address that currently holds by variable given for char[].

How does the strings are stored in the memory?

Strings are stored on the heap area in a separate memory location known as String Constant pool. String constant pool: It is a separate block of memory where all the String variables are held. String str1 = “Hello”; directly, then JVM creates a String object with the given value in a String constant pool.

What is %s in C?

%s is the representation of an array of char char string[10] // here is a array of chars, they max length is 10; char character; // just a char 1 letter/from the ascii map character = ‘a’; // assign ‘a’ to character printf(“character %c “,a); //we will display ‘a’ to stout.

What is a char pointer?

The type of both the variables is a pointer to char or (char*) , so you can pass either of them to a function whose formal argument accepts an array of characters or a character pointer. … It allocates 12 consecutive bytes for string literal “Hello World” and 4 extra bytes for pointer variable ptr .

Is char * a pointer?

8 Answers. char* and char[] are different types, but it’s not immediately apparent in all cases. This is because arrays decay into pointers, meaning that if an expression of type char[] is provided where one of type char* is expected, the compiler automatically converts the array into a pointer to its first element.

Is * a char?

It is a pointer to a char . When declaring a pointer, the asterisk goes after the type and before the identifier, with whitespace being insignificant. These all declare char pointers: char *pointer1; char* pointer2; char * pointer3; char*pointer4; // This is illegible, but legal!

How do I store string in char pointer?

Strings using character pointers Using character pointer strings can be stored in two ways: 1) Read only string in a shared segment. When a string value is directly assigned to a pointer, in most of the compilers, it’s stored in a read-only block (generally in data segment) that is shared among functions.

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.

Is a char pointer a string?

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. file is a stack variable in ListFiles() and you’re returning a pointer to it.

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. C just doesn’t let you do that with arrays.

How do you read a string?
