c语言游戏状态的文件保存载入

在C语言中,可以使用文件I/O操作来保存和载入游戏状态。
首先,需要定义一个结构体来存储游戏状态的各个变量,例如:
```c
struct game_state {
int level;
int score;
char player_name[20];
// 其他变量
};
```
然后,可以使用fopen()函数打开一个文件,使用fprintf()函数将游戏状态写入文件,使用fscanf()函数从文件中读取游戏状态。例如:
```c
void save_game_state(struct game_state state) {
FILE *fp;
fp = fopen("game_state.txt", "w");
fprintf(fp, "%d %d %s", state.level, state.score, state.player_name);
fclose(fp);
}
struct game_state load_game_state() {
struct game_state state;
FILE *fp;
fp = fopen("game_state.txt", "r");
fscanf(fp, "%d %d %s", &state.level, &state.score, state.player_name);
fclose(fp);
return state;
}
```
注意,需要在编译时加上 -lm 参数,以链接数学库。完整的代码示例如下:
```c
#include <stdio.h>
struct game_state {
int level;
int score;
char player_name[20];
};
void save_game_state(struct game_state state) {
FILE *fp;
fp = fopen("game_state.txt", "w");
fprintf(fp, "%d %d %s", state.level, state.score, state.player_name);
fclose(fp);
}
struct game_state load_game_state() {
struct game_state state;
FILE *fp;
fp = fopen("game_state.txt", "r");
fscanf(fp, "%d %d %s", &state.level, &state.score, state.player_name);
fclose(fp);
return state;
}
int main() {
struct game_state state = {5, 100, "Alice"};
save_game_state(state);
struct game_state loaded_state = load_game_state();
printf("Loaded game state: level=%d, score=%d, player_name=%s\n",
loaded_state.level, loaded_state.score, loaded_state.player_name);
return 0;
}
```
