Modify the following code to produce the output shown. Use proper indentation techniques. You must not make any changes other than inserting braces. The compiler ignores indentation in a C++ program. We eliminated the indentation from the following code to make the problem more challenging. [Note: It’s possible that no modification is necessary.]

if ( y == 8 )
if ( x == 5 )
cout << "@@@@@" << endl;
else
cout << "#####" << endl;
cout << "$$$$$" << endl;
cout << "&&&&&" << endl;
a) Assuming x = 5 and y = 8, the following output is produced. @@@@@ $$$$$ &&&&& b) Assuming x = 5 and y = 8, the following output is produced. @@@@@ c) Assuming x = 5 and y = 8, the following output is produced. @@@@@ &&&&& d) Assuming x = 5 and y = 7, the following output is produced. [Note: The last three output statements after the else are all part of a block.] ##### $$$$$ &&&&&
