我猜是一个简单的错误,但是当试图编译我的C代码时我会遇到此错误:
error: expected identifier before '(' token
从这个代码中,我试图为哈希碰撞链接列表设置结构:
typedef struct bN {
MEntry nestedEntry;
struct bN *next;
} bucketNode;
typedef struct bL {
bucketNode *first;
int bucketSize;
} bucket;
struct mlist {
bucket *currentTable;
};
和此代码,我实际上是在链接列表中开始的:
MList *ml_create(void){
MList *temp;
if (ml_verbose){
fprintf(stderr, "mlist: creating mailing listn");
}
if ((temp = (MList *)malloc(sizeof(MList))) != NULL){
temp->currentTable = (bucket *)malloc(tableSize * sizeof(bucket));
int i;
for(i = 0; i < tableSize; i++){
temp->(currentTable+i)->first = NULL; /**ERROR HERE*/
temp->(currentTable+i)->bucketSize = 0; /**ERROR HERE*/
}
}
return temp;
}
您的语法已关闭。你的意思是:
temp->currentTable[i].first = NULL;
temp->currentTable[i].bucketSize = 0;
更改
temp->(currentTable+i)->first = NULL;
为
(temp->currentTable+i)->first = NULL;
