1.用while语句
1 using System; 2 class Sum100 3 { 4 static void Main() 5 { 6 int Sum, i; 7 Sum = 0; i = 1; 8 while (i<=100) 9 { 10 Sum += i; 11 i++; 12 } 13 Console.WriteLine("Sum is" + Sum); 14 } 15 }
2.do-while语句
1 using System; 2 class Sum100 3 { 4 static void Main() 5 { 6 int Sum, i; 7 Sum = 0; i = 1; 8 do 9 { 10 Sum += i; 11 i++; 12 } 13 while (i<=100) 14 Console.WriteLine("Sum is" + Sum); 15 } 16 }
3.for语句(1)
1 using System; 2 3 class Sum100 4 { 5 static void Main() 6 { 7 int Sum, i; 8 Sum = 0; 9 for (i = 1; i <= 100;i++ ) 10 Sum += i; 11 Console.WriteLine("Sum is" + Sum); 12 13 Sum = 0; 14 for (i = 100; i > 0;i-- ) 15 Sum += i; 16 Console.WriteLine("Sum is" + Sum); 17 } 18 }
4.for语句(2)
1 using System; 2 3 class Sum100 4 { 5 static void Main(string[] args) 6 { 7 int Sum, i; 8 9 for (Sum = 0,i = 1; i <= 100;i++ ) 10 Sum += i; 11 Console.WriteLine("Sum is" + Sum); 12 13 14 for (Sum = 0,i <= 100; Sum+i,i++); 15 16 Console.WriteLine("Sum is" + Sum); 17 } 18 }
5.for语句(3)
1 using System; 2 class Sum100 3 { 4 static void Main(string[] args) 5 { 6 int Sum, i; 7 8 for (Sum = 0, i = 1; i <= 100; ) 9 Sum += i++; 10 Console.WriteLine("Sum is" + Sum); 11 12 13 for (Sum = 0,i =1; ;Sum+=i,i++) 14 if(i>100) break; 15 Console.WriteLine("Sum is" + Sum); 16 17 Sum=0;i=1; 18 for(;;) 19 { 20 Sum+=i++; 21 if (i>100) 22 break; 23 } 24 Console.WriteLine("Sum is" + Sum); 25 } 26 }
