Exercise 1: Compile and run program Looping, Fill in the following table. First sum: Second sum: Exercise 2: Program Looping contains two loops implemented with while statements. Rewrite program Looping, replacing the while statements with do-while statements. Fill in the following table. First sum: Second sum:- Exercise 3: Can program Looping be rewritten using a for statement for each loop? Explain. Exercise 4: Rewrite program Looping using a for statement to implement the count- controlled loop. Fill in the following table. First sum: Second sum: Exercise 5: Rerun your program using data file looping.d2. Describe what happens r an error condition was generated, correct your program and rerun the program. Fill in the following table. First sum: Second sum
