visual stdio code is not installed on the computer. So use dev-C + + to write a small program to make your girlfriend happy. Suitable for beginners to practice c + +, full of sense of achievement, so don't spray if you don't like it.
It is rare for dev-c + + to use EGE graphics library, and there are few tutorials, so I will post a note on EGE graphics library in the future. Software download Compiler with ege image library DevCpp.exe - Internet document resources - CSDN Download.
First, let's talk about the logic and key points of the program.
Anxious students can directly look at the source code
logic1. First, the text is presented according to a fixed track.
2. Text and pictures are displayed at the same time, and background music is played at the same time. (divided into two parts, extract the contents from the two arrays)
3. The title text is fixed, and the text information is displayed in the same line like a bullet screen. After all the contents are displayed, the text will be displayed in multiple lines at the same time. The program then loops through program three.
4. The segmentation of each part of the program is divided according to the count of currently playing photos.
main points1.for text
Text track display
First, use a binary array to define the number of text and the size of the storage array
char buff[46][20] = {
"This is,
"My letter",
"In your eyes",
"My letter",
"In your arms",
"In winter,
"Inside the hot milk tea",
"So hot",
"So implicit",
·······
}
Then use a two-dimensional array to represent the track:
Execution code: (pay attention to text color and size)
for (int i = 0; i < 46; i++) { int height = 20 ; //Text height //settextcolor(red); setcolor(EGERGB(rand() % 255, rand() % 255, rand() % 255)); //Sets the color of the text setfont(height, 0, "Regular script"); //Set text width and font outtextxy(arr[i].x, arr[i].y, buff[i]);//Track coordinates and content Sleep(100); }
Text barrage flow
Define an array with static variables. I don't know why I use a > b? 0:1 cannot be executed in the compiler, so I use conditional judgment statements.
Here is to modify the x coordinate of text output.
After displaying a barrage, and then reporting another barrage, it is realized by reading the contents of a two-dimensional array
static int num_flag = 0; static int i = 780; if (i >= -100) { i -= 2; } else { i = 800; num_flag++; if (num_flag > TEXT_NUM - 1) { num_flag = 1; endflag = 1; } } #if switch setcolor(EGERGB(rand() % 200, rand() % 255, rand() % 255)); setfont(40, 0, "Song typeface"); outtextxy(i, 210, text[num_flag]); Sleep(10);
2.for music:
First save music in MP3 format.
#include "mmsystem.h" #pragma comment(lib,"winmm.lib") / / static
Play songs and switch songs
mciSendString("open mymusic1.mp3", NULL, NULL, NULL);//open mciSendString("play mymusic1.mp3", NULL, NULL, NULL);//play
//Play from music 1 to music 2 mciSendString("play mymusic1.mp3", NULL, NULL, NULL);//play mciSendString("pause mymusic1.mp3", NULL, NULL, NULL);//play mciSendString("open mymusic2.mp3", NULL, NULL, NULL);//open mciSendString("play mymusic2.mp3", NULL, NULL, NULL);//play
It should be noted here that these pairs of code must be executed in pairs to realize the function. In addition, the path of mp3 file is not strictly required.
2.for pictures:
Add: some students do not know the relationship between screen coordinates
The red coordinates are the coordinates defined in the function for each character. The distance between the two coordinates is determined by defining the font size.
There is a concept that the source file can only be obtained. What is displayed on the screen is the size of another image format. We pasted the picture in the original format on another picture, so as to complete the scaling of the picture. Specifically, I refer to this blog post.

About picture header files
#include <windows.h>
definition:
be careful screen_img = newimage(250, 270); // The displayed image defines the zoom size
sour_img = newimage(); // File loaded pictures
PIMAGE screen_img; PIMAGE sour_img;
void picture1() { screen_img = newimage(250, 270); //Show pictures sour_img = newimage(); //File loaded pictures char name[100] = ; sprintf(name, "C:\\Users\\Administrator\\Documents\\Tencent Filesgraph_programe\\picture1\\%d.jpg", id); if (id >= PICT_NUM1) { id = 1; } else { id++; } // (id > PICT_NUM) ? 1 : (id++); getimage(sour_img, name); int tempWidth = getwidth(sour_img), tempHeight = getheight(sour_img); putimage(screen_img, 0, 0, 250, 270, sour_img, 0, 0, tempWidth, tempHeight); putimage(290, 310, screen_img); delimage(sour_img); sour_img = NULL; delimage(screen_img); screen_img = NULL; }
It is necessary to say here
1. Forced conversion of picture name. The path must be strict. Replace \ \.
sprintf(name, "C:\\Users\\Administrator\\Documents\\Tencent Files\\1335328142\\FileRecv\\graph_programe\\picture1\\%d.jpg", id);
id is incremented until the total number of pictures starts again. Here, the pictures are renamed in numerical order, such as "1.jpg" ·····················································································.
2. File image acquisition
getimage(sour_img, name);//(defined parameters, picture path and name)
3. Display
putimage(screen_img, 0, 0, 250, 270, sour_img, 0, 0, tempWidth, tempHeight);
Corresponding to (declared display picture variable, 0, 0, display picture zoom size, width, zoom size and height, declared source picture variable, 0, 0, source file width, source file height);
The red and blue matching here shows their corresponding relationship.
putimage(290, 310, screen_img);// Print the presentation file (x starting point, y starting point).
int tempWidth = getwidth(sour_img), tempHeight = getheight(sour_img);//Source file size acquisition putimage(screen_img, 0, 0, 250, 270, sour_img, 0, 0, tempWidth, tempHeight); putimage(290, 310, screen_img);//Print presentation fileSource code
