From basic concepts to advanced techniques, we cover it all. So, if you find yourself pondering, "Who can write my C assignment?", look no further.

**Understanding Pointers: A Fundamental Concept**

Pointers are a fundamental concept in C programming, yet they can be one of the most challenging concepts for students to grasp. Let's delve into a classic pointer problem to shed some light on this topic.

Question 1:

Consider the following C code:

#include stdio.h

void swap(int* a, int* b) {
int temp = *a;
*a = *b;
*b = temp;
}

int main() {
int x = 5, y = 10;
swap(x, y);
printf("x = %d, y = %d", x, y);
return 0;
}

What will be the output of the above code?

Solution:

In the `main` function, we have two variables `x` and `y` initialized to 5 and 10, respectively. We then call the `swap` function, passing the addresses of `x` and `y`. Inside the `swap` function, the values at the addresses pointed to by `a` and `b` are swapped using pointers. Therefore, after the `swap` function is called, `x` will hold the value 10, and `y` will hold the value 5. Hence, the output of the code will be:

```
x = 10, y = 5
```

Dynamic Memory Allocation: A Key Skill

Dynamic memory allocation is another crucial aspect of C programming, allowing for flexible memory management. Let's explore a problem involving dynamic memory allocation.

Question 2:

Write a C program to dynamically allocate memory for an array of integers of size `n`. Initialize the array with consecutive integers starting from 1. Then, print the elements of the array.

Solution:

#include stdio.h
#include stdlib.h

int main() {
int n;
printf("Enter the size of the array: ");
scanf("%d", n);

int *arr = (int*)malloc(n * sizeof(int));
if (arr == NULL) {
printf("Memory allocation failed");
return 1;
}

for (int i = 0; i n; i++) {
arr[i] = i + 1;
}

printf("Elements of the array: ");
for (int i = 0; i n; i++) {
printf("%d ", arr[i]);
}

free(arr);
return 0;
}

In this program, we first prompt the user to enter the size of the array (`n`). We then dynamically allocate memory for an array of integers using the `malloc` function. Next, we initialize the array with consecutive integers starting from 1 using a simple `for` loop. Finally, we print the elements of the array using another `for` loop before freeing the allocated memory using the `free` function.

By mastering concepts like pointers and dynamic memory allocation, you'll be well-equipped to tackle a wide range of programming assignments with confidence.
