Question

用while循环语句求出1+2+3.......+100的和

Answer 1

Sub aaa()
i = 0
While i < 101
a = a + i
i = i + 1
Wend
Debug.Print a
End Sub

Sub bbb()
i = 0
Do While i < 101
a = a + i
i = i + 1
Loop
Debug.Print a
End Sub

Sub ccc()
For i = 1 To 100
a = a + i
Next
Debug.Print a
End Sub

Answer 2

#include <stdio.h>

void main()
{
int i = 0, sum = 0;
while (i++ < 100)
sum += i;
printf("%d", sum);
}

Answer 3

public static void main(String[] args) {
int x =1;
int sum=0;
while(x<=100) {
sum=sum+x;
x++;
}
System.out.println(sum);
}
}

Answer 4

var i=1
var count=0
while(i<=100)
count=count + i
i++
wend
