下列事件過程的功能是：建立一個名為Data1的隨機文件，存放角度值及這些角度的正弦函數(shù)值和余弦函數(shù)值，角度為1，2，3，…，90。請在空白處填入適當?shù)膬?nèi)容，將程序補充完整( )。

A．..\Data1.txtFor Random As #1 Len=10 Put#1,i,Ksc

B．..\Data1.txtFor Random As #1 Len=10 Put#1,Y,Ksc

C．..\Data1.txtFor Random As #1 Put#1,i,Ksc

D．..\Data1.txtFor Random As #1 Put#1,Y,Ksc

A解析：分析程序，程序要將角度值及這些角度的正弦函數(shù)值和余弦函數(shù)值存入Data1文件中。因此，應(yīng)先打開Data1文件，因為Data1文件是隨機文件，要新建并寫入信息，所以使用Random方式打開文件。這里給隨機文件指定長度為10，所以第1個空白處應(yīng)填"..\Data1.txt"For Random As #1 Len=10。要向隨機文件中寫入信息，應(yīng)用Put語句，因此第2空應(yīng)填Put #1,i,Ksc。
