我有一个设置长度的队列实现为一个动态c数组,如下所示:
typedef struct {
float* queue;
int size;
int pointer;
} QueueStruct;
void createQueue(QueueStruct* queueInstance, int size){
queueInstance->queue = malloc(sizeof(float)*size);
queueInstance->size = size;
queueInstance->pointer = 0;
}
void addElementToQueue(QueueStruct* queueInstance,float element){
queueInstance->queue[pointer] = element;
if (queueInstance->pointer == queueInstance.size - 1){
queueInstance->pointer = 0;
} else {
++queueInstance->pointer;
}
}
void freeQueue(QueueStruct* queueInstance){
free(queueInstance->queue);
}
我想实现这个功能:
float* returnQueue(QueueStruct queueInstance){
//I want this function to malloc a new float* and then put the queue in it in the
// correct order, from start to finish, as pointed too by the pointer.
//Im not sure how to do this.
}
任何帮助,将不胜感激。
编辑:更正了一个愚蠢的编程错误 - 这是我程序中实际内容的简化版本。
