Pointer: Pointer, the name itself references the purpose of the pointer. Pointers point to a location in memory. Pointer is a special type of variable to store the address of the memory location, which can be accessed later. If an asterisk “” operator is present before the variable, then that variable is referred as pointer variable. It is also called as dereferencing or indirection operator. Pointer is just a type of variable that stores the addresses of other variables. Using pointers, we can access the address of a variable; the data stored in that variable can be retrieved. Syntax of pointer variable declaration: <variable-type> <variable-name>; Example for pointer variable declaration: //definition of pointer variable int ptrvar; Where, “int” is the variable type. “ ptrvar” is the pointer variable name. Pointer will allow the user to indirectly access and manipulate the data contents of the variable. A pointer variable will hold the address of the data contents.

Program Plan Intro

Pointer:

Pointer, the name itself references the purpose of the pointer. Pointers point to a location in memory.

Pointer is a special type of variable to store the address of the memory location, which can be accessed later.

If an asterisk “” operator is present before the variable, then that variable is referred as pointer variable.

It is also called as dereferencing or indirection operator.

Pointer is just a type of variable that stores the addresses of other variables.

Using pointers, we can access the address of a variable; the data stored in that variable can be retrieved.

Syntax of pointer variable declaration:

<variable-type> <variable-name>;

Example for pointer variable declaration:

//definition of pointer variable

int ptrvar;

Where,

“int” is the variable type.

“ ptrvar” is the pointer variable name.

Pointer will allow the user to indirectly access and manipulate the data contents of the variable. A pointer variable will hold the address of the data contents.

Note:

When the symbol “&” is placed prior the pointer variable, it will hold address of the pointer variable.

When the symbol “*” is placed prior the pointer variable, it will hold the value of the pointer variable.

Instructions: In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString(). This preserveString() function has the following description: Return type - void Name - preserveString Parameters The string Length of the string Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function. Please Finish the code ASAP: This is my current given code: #include<stdio.h>#include<string.h> #define STR_MAX_SIZE 100 void preserveString(char*, int); int main(void) { char str[STR_MAX_SIZE]; printf("Enter string: "); fgets(str, STR_MAX_SIZE, stdin); preserveString(str,…

In operator overloading, if you overload == as a nonmember function, you are allowed to pass one or both objects as parameters O True False
