C語言鏈表實現冒泡法排序

功能是：從鍵盤輸入字符以空格隔開 當輸入q或者Q時按回車表示輸入結束

先放出main函數

int main(){
    
    MyNode *myNode = (MyNode *)malloc(sizeof(MyNode));
    if (NULL == myNode) {
        return 0;
    }
    
    getNum(myNode);
    sortList(myNode);
    printStr(myNode);
    freeStr(myNode);
  
    return 0;
}

    printf("please input num and end with q/Q\n");
    scanf("%s", s);
    
    while ((strcmp(s, "q") != 0) && (strcmp(s , "Q") != 0)) {

        if (NULL == temp) {
