### Dynamic Array Creation in C#### Question 15Write the C function that will create an instance of the structure for the dynamic array defined below and initialize the fields in the structure to reflect that space for 20 values have been allocated in the dynamic array. The function’s parameter must match the call shown below.```ctypedef struct dynArrStruct { int *arr; /* pointer to the dynamic array */ int allocated; /* amount of space currently allocated for the dynamic array */ int inUse; /* number of values currently stored in the dynamic array */} dynArr;void main() { dynArr *a1; a1 = create(); /* write the function to match this call */}/* Function Definition */dynArrStruct *create(unsigned n) { dynArrStruct* matrix; matrix = malloc(sizeof(*matrix)); matrix->allocated = n; matrix->inUse = 0; matrix->arr = malloc(sizeof(int *) * n); for(int i = 0; i < n; i++) { matrix->arr[i] = malloc(sizeof(int) * (n - i)); } return matrix;}```#### Explanation- **Structure Definition**: A `typedef` struct named `dynArrStruct` is defined with three components: - `int *arr`: A pointer to the dynamic integer array. - `int allocated`: An integer representing the total space allocated for the array. - `int inUse`: An integer tracking the number of current elements stored in the array.- **Main Function**: In `main()`, a pointer `a1` of type `dynArr` is declared and assigned the result of the `create()` function, which you must implement.- **Create Function**: - The function `create()` accepts an unsigned integer `n` as an argument, which determines the size of the dynamic array. - `dynArrStruct* matrix`: A pointer to `dynArrStruct` is declared. - `matrix` is allocated memory using `malloc()`. - `matrix->allocated` is set to `n`. - `matrix->inUse` is initialized to `0`, indicating no elements are currently stored. - Memory for the integer array `matrix->arr` is allocated. - An inner loop allocates diminishing amounts of additional memory for each element in the array

Pointers A pointer is basically a reference to an object or a function. In fact, it is a variable that holds memory address. This address is the location of some other variable or object in memory. For example, if one variable contains the address of another variable, first one is said to point to the second one. Pointers may have many uses, such as to make functions implement “call-by-reference” methodology and to construct dynamic arrays or structures at run-time. a) Write a complete C program that demonstrates the usage of call-by-reference technique needed for swapping.  Develop a call-by-value version to see that changes done to the parameters inside the function are lost. b) Write a complete C program that implements below given user-defined function prototypes for arrays-of-integers.  void input_1d_array( int*, int );  void output_1d_array( int*, int );  int sum_1d_array( int*, int );  float average_1d_array( int*, int );  Test each function separately! c) [if time allows]…

Pointers with Arrays and Function Please use C Language to code 1. Write a program that accepts the blood pressure as a floating point value into a five- element array, called bp. The program has a module that uses pointer notation called hbp that checks whether the patients' blood pressure is high or normal. hbp has a pointer called bpPtr and an integer called arrsize has its arguments. The blood pressure of the patient is high if it is greater than 1.6 otherwise, it is normal.The module outputs to the patient that they have high blood pressure and that they are to monitor their cholesterol levels over the next 7 days; otherwise, it outputs a message that the blood pressure level is normal.
