The function should allocate a new array populated with the contents of the original array plus the new value inserted at the given index. The originally array should be freed. The following sections provide a detailed description of this function: Make sure your source code is well-commented, consistently formatted, uses no magic numbers/values, follows programming best-practices, and is ANSI-compliant. It is expected to have the program output28. Which statement of the following is the most appropriate? Group of answer choices The size of a dynamic array needs to be determined at compilation. Such behavior, determined at compile time, is called dynamic behavior. Dynamic behavior is more flexible than decisions that are made at run time (i.e., static behavior). The size of a dynamic array does not need to be determined until a program is running. Such behavior, determined at run time, is called dynamic behavior.

- Can someone please help and explain the C code that I would need for this. I am new to C and would like some help. I also do not know how to check the storage for the cache on my microsoft surface 2 computer. Define Data Structures Large Arrays: Define a large array in memory. The size should be chosen based on the cache size of the target processor. Choose a size that is larger than the L3 cache of the processor. You will need to look up the sizes of the L1, L2, and L3 for the processor you are using. Access Area: Access areas within the L1, L2, L3, and larger than the L3 cache. You must read memory the same number of times for each, but simply access more memory for each. Sequential Access: Access the elements of the first array sequentially. This pattern benefits from spatial locality, as once a cache line (containing a part of the array) is loaded into the cache, subsequent accesses to nearby elements will be faster. Random: Access the elements of the second array in a…Convert from C to C++ .Thank you. / include all required libraries#include<stdio.h>#include<stdlib.h>#include<sys/types.h>#include<sys/wait.h>#include<unistd.h> // variable to store number of generationsint num_generations; // function to print the generationsvoid printGeneration(int n){// stop if number of generations are reachedif(n>num_generations)return; // create a forkpid_t p = fork(); // generate new generationsif(p==0)printGeneration(n+1);else if(p>0)wait(0); // wait until child process terminates // print the present generationif(p!=0){// if n is 0if(n==0)printf("Parent.

In segmentation, a logical address always has a length of 32 bit. In order to translate logical into physical addresses, the memory management unit uses the segment part of the logical address to determine the start address in the segment table and adds the offset to this to get the physical address. In segmentation, the logical address consists of a segment part and an offset. The segment length is limited by the maximum possible segment number. When applying segmentation, processes are only allowed to access the memory within their segments. Segments can be assigned access rights and privilege levels.
