在Visual FoxPro (VFP) 中,有多种方法可以编写一个程序来计算1到100的和。以下是几种常见的方法:

方法1:使用DO WHILE循环

```vfp

CLEAR

s = 0

i = 1

DO WHILE i <= 100

s = s + i

i = i + 1

ENDDO

? s

```

方法2:使用FOR循环

```vfp

CLEAR

s = 0

FOR i = 1 TO 100

s = s + i

ENDFOR

? s

```

方法3:使用SET TALK OFF和CLEAR

```vfp

SET TALK OFF

CLEAR

s = 0

FOR K = 1 TO 100

s = s + K

ENDFOR

? s

SET TALK ON

```

方法4:使用阶乘的累加

```vfp

CLEAR

s = 0

FOR i = 1 TO 100

s = s + i

ENDFOR

? s

```

方法5:使用嵌套循环

```vfp

SET TALK OFF

FOR x = 0 TO 100

FOR Y = 0 TO 100

FOR Z = 0 TO 100

IF 3 * x + 5 * Y + Z / 3 = 100 AND x + Y + Z = 100

" 公鸡、母鸡、小鸡的数量分别是: " ,x,Y,Z

ENDIF

ENDFOR

ENDFOR

ENDFOR

SET TALK ON

```

这些方法都可以有效地计算1到100的和。你可以根据自己的需求和编程习惯选择合适的方法。
