这都是些什么

@中华星尊
结构体有些烦
比如
typedef struct people{
char*name;
int funny;
int number;
struct people*this_t;
}p;
int main(int argv,char*args[]){
p bjgt,*hj;
hj=&bjgt;
hj->this_t=&bjgt;
hj->this_t->name="烦人";
hj->this_t->funny=100;
return 0;
}

typedef struct p使以后用p定义结构体变量

接下来，hj指向bjgt

然后hj->this_t=&bjgt实际上将这个结构体people首尾相连了

然后字符串name是‘烦人’
funny赋为100

不过int argv, char *args[]是要干什么函数问题我再了解了解

不再是黑窗
#include <SDL2/SDL.h>
#include<SDL2/SDL_image.h>
int main(int,char**){
SDL_Window*win=NULL;
SDL_Surface*Surface=NULL;
SDL_Texture*Texture=NULL;
SDL_Renderer*r=NULL;
SDL_Init(SDL_INIT_EVERYTHING);
win=SDL_CreateWindow("六",0,0,400,600,0);
Surface=IMG_Load("/sdcard/hello.jpg");
r=SDL_CreateRenderer(win,-1,SDL_RENDERER_ACCELERATED);
Texture=
SDL_CreateTextureFromSurface(r,
Surface);
SDL_FreeSurface(Surface);
SDL_RenderClear(r);
SDL_RenderCopy(r,Texture,NULL,
NULL);
SDL_RenderPresent(r);
SDL_Delay(3000);
SDL_DestroyTexture(Texture);
SDL_DestroyRenderer(r);
SDL_DestroyWindow(win);
return 0;
}
