关于VB迭代法的用法，帮忙用VB写下代码。。

Private Sub Form_Click()

Form1.AutoRedraw = True

Cls

Dim P15 As Single, P20 As Single, A As Single, Tt As Single

Dim T As Single, P151 As Single, I As Integer

Dim E As Single

E = Exp(1)

T = Val(InputBox("t=", "输入"察喊, 1))

P20 = Val(InputBox("p20=", "输入", 30))

Tt = T

P15 = P20

Print "t="T, "p20="P20

I = 0

Do

I = I + 1

P151 = P15

A = 186.9696 / P15 ^ 2 + 0.4862 / P15

P15 = P20 / E ^ -A * Tt * (1 + 0.8 * A * Tt)

Print I, "p151="P151, "p15="P15

Loop While Abs(P15 - P151) >迅没野= 0.0005

Print "最后结果为：亩喊p15="P15

End Sub

#include <stdio.h>型做

float value()

{

float x0, x1

x0 = 0

x1 = cos(x0)

while (abs(x0 - x1) >= 0.000001)

{

x0 = x1

x1 = cos(x0)

}

return x1

}

void main()

{

printf("迭代方法求方程：卜肢衡cos(x)-x=0的解为%f\n", value())

}
