首先,需要确保 `pgdata` 数组长度足够大,可以容纳 `wave_count` 个元素。如果数组长度不足,需要增加数组长度或者使用动态内存分配。
其次,可以将重复的赋值语句提取出来,只在循环外部执行一次,避免重复赋值带来的性能消耗。同时,可以使用指针操作,避免使用数组下标访问数组元素,提高代码效率。
以下是优化后的代码:
```
pgdata->IsDisble = 0;
pgdata->CurDataCount = 0;
pgdata->PointBufCount = 0;
pgdata->WaveColor = *wave_color;
PGDATA* pgdata_ptr = pgdata;
const COLOR* wave_color_ptr = wave_color;
const COLOR* pspn_color_ptr = pspn_color;
const STATUS* pspn_status_ptr = pspn_status;
const POINT** point_buf_ptr = point_buf;
for (int i = 0; i < wave_count; i++) {
pgdata_ptr->IsDisble = 0;
pgdata_ptr->CurDataCount = 0;
pgdata_ptr->LastDataCount = 0;
pgdata_ptr->PointBufCount = 0;
pgdata_ptr->pPointBuffer = *point_buf_ptr++;
pgdata_ptr->WaveColor = *wave_color_ptr++;
pgdata_ptr->PspnColor = *pspn_color_ptr++;
pgdata_ptr->PointStatus = *pspn_status_ptr++;
pgdata_ptr++;
}
```
