For the memory locations in the table above, write C code to sort the data from lowest to highest, placing the lowest value in the smallest memory location shown in the figure. Assume that the data shown represents the C variable called Array, which is an array of type int, and that the first number in the array shown is the first element in the array. Assume that this particular machine is a byte-addressable machine and a word consists of four bytes.b. For the memory locations in the table above, write MIPS code to sort the data from lowest to highest, placing the lowest value in the smallest memory location. Use a minimum number of MIPS instructions. Assume the base address of Array is stored in register $s6.Create a c ++ program keeping in mind the concepts about Pointers (Pointers). Instructions: Write a program to find the maximum of a set of integers within an array. The program should ask the user to enter each of the values. At the end the program prints a pointer to point to the maximum value. The example is shown in the image Note create the program in c ++

Structure array is used in this program to store and display records for many students. It can store “n” number of students record by declaring structure variable as ‘struct student record[n]“, where n can be 3 or 10 etc. Determine the highest grade and number of student passed and failed.NOTE:Your source code must display any of the given sample output below.It means your source code should be flexible enough to meet any of the given sample output.Your source code output must be identical to any of the given sample output.It means you have to strictly follow what are the displayed text, labels, casing of characters in the sample output.Passing Grade is 70-100. Sample Outputs:Using C++ programming language: Assume intptr is a pointer to an int. Write a statement that will dynamically allocate an array of 100 integers and store its address in intptr. Also, write a statement that will free the memory allocated in the statement you just wrote.
