///要開檔案指標 fopen()

#include <stdio.h>

int main()

{

    FILE * fout = fopen("檔名","模式");

    printf("Hello World\n")

    fprintf(fout,"Hello World在檔案裡\n")

}

{

要開心的GLUT專案，必須更改freeglut的lib檔裡的libglut32檔

#include <stdio.h>

#include <GL/glut.h>

float teapotX = 0,teapotY = 0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotX,teapotY,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void mouse(int button ,int state,int x,int y)

{

    teapotX = (x-150)/150.0;

    teapotY = (150-y)/150.0;

    display();

}

int main(int argc,char **argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("Week12");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

#include <stdio.h>

#include <GL/glut.h>

float teapotX = 0,teapotY = 0;

FILE * fout = NULL;

FILE * fin = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotX,teapotY,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void mouse(int button ,int state,int x,int y)

{

    teapotX = (x-150)/150.0;

    teapotY = (150-y)/150.0;

    if(state==GLUT_DOWN)

    {

        if(fout==NULL) fout = fopen("file4.txt","w");

        fprintf(fout,"%f %f\n",teapotX,teapotY);

    }

    display();

}

void keyboard(unsigned char key,int x,int y)

{

    if(fin==NULL)

    {

        fclose(fout);

        fin = fopen("file4.txt","r");

    }

    fscanf(fin,"%f%f",&teapotX,&teapotY);

    display();

}

int main(int argc,char **argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("Week12");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

按右鍵properites的第二個bulid targets把路徑改成.

這裡會做修改

更改檔案位址，將freeglut.dll放置week12-4的資料夾中

按執行便能成功叫出茶壺，並用滑鼠移動位址

最後github push 上傳到git 有final
