- Suppose the following code: int a, b, c;char array[100];void f(int& val){char* arr = new char[100];for(int i = 0; i < val; ++i){arr[i] = i*i;}}int main(){int myValue = 123;f(myValue);return 0;} Think about which section of process memory each part of this program would occupy during execution. Then, match items on the left with their storage locations on the right.in fedora 37 1. Create a directory named Module9 and navigate to that directory. 2. Copy the file pay.dat from Module8 to Module9. Here it is again, just in case: 0001:John Smith:15.40 0002:Jane Smith:15.41 0003:George Jungle:12.10 0004:Ursula Jungle:16.11 3. Using a pipe symbol for filtering and sort the data to stdout. Enter: cat pay.dat | sort 4. Now, on your own, using a pipe symbol for filtering and sort the data in descending order to stdout and append that to a file named SortPay.dat. 5. Copy pay.dat to three files named: pay10,dat, pay12.dat, and pay02.txt. You may need to use multiple commands. 6. Use pattern matching to locate only pay02.txt. 7. Enter the command to remove pay2.dat and redirect both stdin and stdout to a file named RemovePay.txt. 8. Run the command in step 7 again. 9. Display the contents of RemovePay.txt 10.
