Week12

step01

程式碼:

#include <stdio.h>
	int main()
	{
	FILE * fout = fopen("file.txt","w");
	printf("Hello World\n");
	fprintf(fout,"Hello World在檔案裡\n");
	}

step02

到檔案總管中，有新的file.txt檔案

step03

程式碼:

#include <stdio.h>
	int main()
	{
	FILE * fin = fopen("file.txt", "r");
	char line[100];
	fscanf(fin, "%s" , line);
	printf("從file.txt讀到了: %s\n",line);
	fscanf(fin , "%s" , line);
	printf("從file.txt讀到了: %s\n",line);
	}

step04

執行 :

（讀取到空格 所以字分開)

程式碼:

#include <stdio.h>
	int main()
	{
	int a[10] = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100};
	int b[10] = {};
	FILE * fout = fopen("file3.txt","w");
	for(int i=0 ; i<10 ; i++)
	{
	printf("%d ",a[i]);
	fprintf(fout,"%d ",a[i]);
	}
	printf("\n");
	fprintf(fout,"\n");
	fclose(fout);
	FILE * fin = fopen("file3.txt","r");
	for(int i=0 ; i<10 ; i++)
	{
	fscanf(fin,"%d", &b[i]);
	printf("b%d:%d ",i, b[i]);
	}
	fclose(fin);
	}

step05

執行: 

step06

程式碼:

#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)
	{
	if(state==GLUT_DOWN)
	{
	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();
	}

(用滑鼠點會移動位置)

step07

(座標點會存在檔案總管中(freeglut/bin)資料夾裡面)

執行 : 

(按滑鼠的畫面)

(按空白鍵畫面會重複一次)

程式碼：

#include <stdio.h>
	#include <GL/glut.h>
	FILE * fout = NULL;
	FILE * fin = NULL;
	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)
	{
	if(state==GLUT_DOWN)
	{
	teapotX = (x-150)/150.0;
	teapotY = (150-y)/150.0;
	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);
	glutMouseFunc(mouse);
	glutKeyboardFunc(keyboard);
	glutMainLoop();
	}

step08

工作目錄不合理，要修改

step09

將freeglut.dill複製到專案裡

需要修改 (Release)

step10

上傳檔案git指令

1. git指令

2. cd desktop

3. git clone https://github.com/你的帳號/2023graphicsa

4. cd 2023graphicsa

5. start .

6. git add . 

7. git status

8. git config --global user.email "電子郵件"

9. git config --global user.name "帳號名chiche0306"

10. git commit -m "week"

11. git push
