4.作業：機器人擺動作
開啟code blocks→File→New→Project→Console application
打上程式碼，可以在自己的資料夾上看到一個新檔案，打開資料夾，裡面可以看到輸出的東西
#include <stdio.h>
FILE * fout=NULL; ///宣告一個檔案指標
int main()
{ ///檔案寫黨
fout=fopen("filename.txt","w+"); ///我們要開的檔案
for(int i=0;i<20;i++){
fprintf(fout,"Hello World\n"); ///印出來的檔案
}
}
再加上一些程式碼，多加一個檔案
#include <stdio.h>
FILE * fout2=NULL; ///NOW2 寫另一個檔案
FILE * fin2=NULL; ///NOW2 讀另一個檔案
float angle[20]; ///NOW2 我們有20個關的角度
int main()
{ ///檔案寫黨
fout2=fopen("motion.txt","w+"); ///NOW2 另一個有關節的檔案
for(int i=0;i<20;i++){
fprintf(fout2," %.2f ",angle[i]); ///另一個有關節的檔案
} ///加空格是因為怕數字黏起來
///若沒有加空格，數字就會黏起來
fprintf(fout2,"\n");
}
下載檔案
將檔案移至桌面並開啟
將檔案移至桌面並開啟
將lib打開
將此檔案複製並貼上
將貼上的檔案重新命名為libglut32.a
File→New→Project
選取 GLUT project
輸入名稱，將檔案儲存在桌面
將老師提供的程式碼貼上去後，紅色茶壺可以用滑鼠進行旋轉，顏色可以依照自己的喜好做修改
