while (val < 10) { Console.WriteLine(val); val++; } for(int val = 0; val < 10; val++) { Console.WriteLine(val); } for(int val = 0; val <= 10; val++) { Console.WriteLine(val); } for(int val = 0; val < 10; val--) { Console.WriteLine(val); } int val = 0; do while (val < 10) { Console.WriteLine(val); val++; } 5. Question : (TCO 5) A block of statements within the body of a FOR loop must be surrounded with _____. curly braces {} parentheses () square brackets [] None of the above 6. Question : (TCO 5) What output will this set of statements produce? int a = 1; while (a < 1) { Console.Write("{0}\t", a); a++; } Console.Write("{0}\t", a); An infinite loop An exception 1 1 1 7. Question : (TCO 5) In this code, the variable _____ is a counter and the variable _____ is an accumulator. double total = 0, weight = 2.0, limit =10, max = 50; int track = 0; for (int num = 0; num <= limit; num++ ) { total = total + weight * num; if (total <= max) track++; } num, track total, track track, total weight, limit 8. Question : (TCO 5) In this code, the inner FOR loop _____. int i = 1, j = 1; for (i = 1; i < 4; i++) { for (j = 1; j < 4; j++) { Console.Write("{0}{1} ", i, j); } } contains a syntax error is nested executes three times executes four times 9.

Question : (TCO 10) Which of the following are best programming practices?
