鯉魚-Week14

 1、練習開檔、寫檔、關檔

#include <stdio.h>

int main()

{

    FILE * fout = fopen("file.txt","w+");

    printf("Hello World\n");

    fprintf(fout,"Hello World\n");

    fclose(fout);

}

2、練習讀檔

#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("讀到了字串：%s 及整數%d\n",line,a);

    fclose(fin);

}

3、上禮拜的加東西

#include <GL/glut.h>

#include <stdio.h>

float angle[20],oldX=0;

int angleID=0;

FILE *fout = NULL;

void myWrite(){

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

    for(int i=0;i<20;i++){

        fprintf(fout,"%.2f",angle[i]);

    }

}

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

    if(key=='1')angleID=1;

    if(key=='2')angleID=2;

    if(key=='3')angleID=3;

    if(key=='4')angleID=4;

}

void mouse(int button, int state, int x, int y){ //mouse按下去

    oldX = x;

}

void motion(int x, int y){

    angle[angleID] += (x-oldX);

    oldX = x;

    glutPostRedisplay(); //重畫畫面 Re display

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.2); //白色身體

    glPushMatrix();//右半邊

        glTranslatef(0.3,0.5,0);//等一下掛在0.5,0.5

        glRotatef(angle[0],0,0,1);//z軸旋轉

        glTranslatef(-0.3,-0.4,0);

        glColor3f(1,0,0);//紅色的

        glRectf(0.3,0.5,0.8,0.3);//手臂

        glTranslatef(0.8,0.4,0);

        glRotatef(angle[1],0,0,1);

        glTranslatef(-0.8,-0.4,0);

        glColor3f(0,1,0);//綠色的

        glRectf(0.8,0.5,1.1,0.3);//下手臂

    glPopMatrix();

        glPushMatrix();//左半邊

        glTranslatef(-0.3,0.5,0);//等一下掛在0.5,0.5

        glRotatef(angle[2],0,0,1);//z軸旋轉

        glTranslatef(0.3,-0.4,0);

        glColor3f(1,0,0);//紅色的

        glRectf(-0.3,0.5,-0.8,0.3);//手臂

        glTranslatef(-0.8,0.4,0);

        glRotatef(angle[3],0,0,1);

        glTranslatef(0.8,-0.4,0);

        glColor3f(0,1,0);//綠色的

        glRectf(-0.8,0.5,-1.1,0.3);//下手臂

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(600,600);

    glutCreateWindow("week13 rect TRT");

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

}

4、

#include <GL/glut.h>

#include <stdio.h>

float angle[20],oldX=0;

int angleID=0;

FILE *fout = NULL, * fin = NULL;

void myWrite(){

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

    for(int i=0;i<20;i++){

        printf("%.2f",angle[i]);

        fprintf(fout,"%.2f",angle[i]);

    }

    printf("\n");

    fprintf(fout,"\n");

}

void myRead(){

    if(fout!=NULL){fclose(fout);fout=NULL;}

    if(fin=NULL)fin = fopen("file.txt","r");

    for(int i=0;i<20;i++){

        fscanf(fin,"%f",&angle[i]);

    }

    glutPostRedisplay();

}

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

    if(key=='r'){myRead();}

    if(key=='1')angleID=1;

    if(key=='2')angleID=2;

    if(key=='3')angleID=3;

    if(key=='4')angleID=4;

}

void mouse(int button, int state, int x, int y){ //mouse按下去

    oldX = x;

}

void motion(int x, int y){

    angle[angleID] += (x-oldX);

    oldX = x;

    glutPostRedisplay(); //重畫畫面 Re display

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.2); //白色身體

    glPushMatrix();//右半邊

        glTranslatef(0.3,0.5,0);//等一下掛在0.5,0.5

        glRotatef(angle[0],0,0,1);//z軸旋轉

        glTranslatef(-0.3,-0.4,0);

        glColor3f(1,0,0);//紅色的

        glRectf(0.3,0.5,0.8,0.3);//手臂

        glRotatef(angle[1],0,0,1);

        glTranslatef(-0.8,-0.4,0);

        glColor3f(0,1,0);//綠色的

        glRectf(0.8,0.5,1.1,0.3);//下手臂

    glPopMatrix();

        glPushMatrix();//左半邊

        glTranslatef(-0.3,0.5,0);//等一下掛在0.5,0.5

        glRotatef(angle[2],0,0,1);//z軸旋轉

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    //glutInitWindowSize(600,600);

    glutCreateWindow("week13 rect TRT");

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

}

5、鬧鐘程式

#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);   //1000代表1秒

    printf("設定好鬧鐘,再回去睡\n");

}

void display()

{

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week14 timer");

    glutTimerFunc(3000,timer,0);   //3秒後，叫timer

    glutDisplayFunc(display);

    glutMainLoop();

}

6、鬧鐘加鈴聲

#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("設定好鬧鐘,再回去睡\n");

}

void display()

{

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week14 timer");

    glutTimerFunc(3000,timer,0);

    glutDisplayFunc(display);

    glutMainLoop();

}
