To write an append function in C, you can create a function that takes in the array to which you want to append a new element, the size of the array, and the new element to be appended. Within the function, you can allocate memory for a new array that is one element larger than the original array, copy the elements from the original array to the new array, and then add the new element at the end. Finally, you can free the memory of the original array and return the new array. This way, you can dynamically append elements to an array in C. **

Both markets offer opportunities for profit, but they also come with their own risks and challenges. It is important to thoroughly research and understand both markets before deciding which one is better suited to your investment strategy. **
