## Usage / 使用示例

```c
#include "code.c"

int main() {
    const char* text = "This is a sample text for searching...";
    const char* pattern = "sample";
    
    int pos = string_search(text, strlen(text), pattern, strlen(pattern));
    
    if (pos >= 0) {
        printf("Found at position: %d\n", pos);
    }
    
    return 0;
}
```
