Question 4: What will be the output of the following C# code?
static void Main(string[] args) { int x = 0; while (x < 20) { while (x < 10) { if (x % 2 == 0) { Console.WriteLine(x); } x++; } } Console.ReadLine(); } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
0 2 4 6 8 10 12 14 16 18 20
0 2 4 6 8
0 2 4 6 8 10
Question 5: What will be the output of the following C# code?
static void Main(string[] args) { int x; x = Convert.ToInt32(Console.ReadLine()); int c = 1; while (c <= x) { if (c % 2 == 0) { Console.WriteLine("Execute While " + c + "\t" + "time"); } c++; } Console.ReadLine(); } for x = 8. Execute while 1 time Execute while 3 time Execute while 5 time Execute while 7 time Execute while 2 time Execute while 4 time Execute while 6 time Execute while 8 time Execute while 1 time Execute while 2 time Execute while 3 time Execute while 4 time Execute while 5 time Execute while 6 time Execute while 7 time Execute while 2 time Execute while 3 time Execute while 4 time Execute while 5 time
Question 7: Correct syntax for while statement is:
while { }(condition); while(condition) { }; while(condition) { } while(condition); { }
Question 9: What will be the output of the following C# code?
static void Main(string[] args) { int i = 0; while (i <= 50) { if (i % 10 == 0) continue; else break; i += 10; Console.WriteLine(i % 10); } }
code prints output as 0 0 0 0 0
code prints output as 10 20 30 40 50
infinite loop but doesn't print anything
Code generate error
