----------------------------------------------------------------------------------------------------------------
●01
打開codeblocks
new project > console application
●02
輸入程式碼
印出20個Hello World
PS*小黑窗不會顯示 在檔案資料夾裡面的文字檔.txt
◎程式碼
#include <stdio.h> ///(0)
FILE * fout=NULL; ///(1)宣告 檔案指標 變數
int main()
{
fout = fopen("filename.txt","w+");///(2) 開檔案
for(int i=0;i<20;i++)
{
fprintf(fout,"Hello World");
}
}
●03
輸入程式碼
印出20個浮點數
PS*小黑窗不會顯示 在檔案資料夾裡面的文字檔.txt
◎程式碼
#include <stdio.h> ///(0)
FILE * fout=NULL;
///(1)宣告 檔案指標 變數
///(1)宣告 檔案指標 變數
float angle[20];
int main()

///(2) 開檔案
///(2) 開檔案
for(int i=0;i<20;i++)
{
fprintf(fout,"%.1f ",angle[i]);
}
}
。打開 codeblocks Files> New>project>GLUT
。到google搜尋 freegult windows
下載 Download freeglut 3.0.0 for MinGW
。解壓縮 freeglut。打開 lib 找到 freeglut.a 並複製
。把 freeglut.a 改為 libglut32.a
。複製 freeglut連接位置
。找到 程式碼 main.c 並打開 執行完成!
。找到 程式碼 main.c 並打開 執行完成!
