開啟檔案 fopen 需要先有指標
FILE*fin=fopen(file.txt,"w");
week14-2
#include <stdio.h>
int main()
{
FILE * fout =fopen("file2.txt", "w+");
fprintf(fout, "angle1 %d\n",999);
fclose(fout);
char line[200];
int a;
FILE *fin=fopen("file2.txt","r");
fscanf(fin, "%s %d",line,&a);
printf("讀到的字串:%s 及整數:%d\n" ,line,a);
fclose(fin);
}
step01-3 使用上禮拜的程式碼來製作動畫
紅色是新增程式碼

把工作區中的雙引號的內容改成小數點
用notepad++改目錄的位置
弄完可以回去build log 看有沒有改成功
再來把桌面freeglut資料夾中的freeglut.dll 手動複製到現在在做的檔案裏面
鬧鐘計時器
#include <GL/glut.h>
#include <stdio.h>
void timer(int t){
printf("鬧鐘%d,我起床了\n",t);
printf("設定下一個鬧鐘\n");
glutTimerFunc(1000,timer,t+1);
printf("設好鬧鐘 再回去睡");
}
void display()
{
}
int main(int argc,char ** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Week14");
glutTimerFunc(3000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}
新增聲音
!!!!!!!!!!!!!!!!!!到teams下載do.wav放在freeglut的bin
#include <GL/glut.h>
#include <mmsystem.h>
#include <stdio.h>
void timer(int t){
printf("鬧鐘%d,我起床了\n",t);
PlaySound("do.wav",NULL,SND_ASYNC);
printf("設定下一個鬧鐘\n");
glutTimerFunc(1000,timer,t+1);
printf("設好鬧鐘 再回去睡");
}
void display()
{
}
int main(int argc,char ** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Week14");
glutTimerFunc(3000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}
