(1)使用貝殼專案
程式碼--
#include <stdio.h>
FILE * fout = NULL,*fin = NULL;
int main(int argc,char**argv)
{
    if(fout==NULL)
        fout = fopen("output.txt","wt");
        fprintf(fout,"Hello World\n");
        return 0;
}

茶壺讀取

.加入檔案

程式碼--

#include <GL/glut.h>

#include <stdio.h>

FILE * fout = NULL,*fin = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

void motion(int x, int y)

{

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

    fprintf(fout, "%d %d\n",x,y);

    printf("%d %d\n",x,y);

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("3D");

    glutDisplayFunc(display);

    glutMotionFunc(motion);

    glutMainLoop();

}
