How do you access a member of a structure using a structure pointer in C?*1 pointWith the dot operator (.)With the arrow operator (->)With the ampersand (&)With the asterisk (*

If a variable is a pointer to a structure, then which of the following operator is used to access data members of the structure through the pointer variable? ans. & . -> *

Identify the incorrect syntax for a pointer to a structure:Assuming the structure: struct temp { int b; } *obj;

ObjectiveIn this challenge, you will learn to implement the basic functionalities of pointers in C. A pointer in C is a way to share a memory address among different contexts (primarily functions). They are primarily used whenever a function needs to modify the content of a variable that it does not own.In order to access the memory address of a variable, , prepend it with sign. For example, &val returns the memory address of .This memory address is assigned to a pointer and can be shared among various functions. For example, will assign the memory address of to pointer . To access the content of the memory to which the pointer points, prepend it with a *. For example, *p will return the value reflected by and any modification to it will be reflected at the source (). void increment(int *v) { (*v)++; } int main() { int a; scanf("%d", &a); increment(&a); printf("%d", a); return 0; } TaskComplete the function void update(int *a,int *b). It receives two integer pointers, int* a and int* b. Set the value of to their sum, and to their absolute difference. There is no return value, and no return statement is needed.Input FormatThe input will contain two integers, and , separated by a newline.Output FormatModify the two values in place and the code stub main() will print their values.Note: Input/ouput will be automatically handled. You only have to complete the function described in the 'task' section.Sample Input45Sample Output91Explanation
