好日子全部,链接列表 - 插入功能
我试着准备一个带有链表的学生信息系统。我创建了一个名为course的scturct。用于插入过程;我将在main函数中调用void insertCourse(CourseNodePtr * cr,char * code)。当我编译时,我看到了这些错误; “insertCourse”参数2的不兼容类型。功能“insertCourse”的参数太少。有没有人评论这个问题?非常感谢..
/* Function Prototypes */
void insertCourse(CourseNodePtr* cr, char* code);
/* Main func starts here */
int main(void)
Course course_code;
switch (choice) {
case 1:
insertCourse(&startPtr, course_code);
break;
/* Insert course function */
void insertCourse(CourseNodePtr* cr, char* code)
{
CourseNodePtr newPtr; /* New node pointer */
CourseNodePtr previousPtr; /* previous node pointer in list */
CourseNodePtr currentPtr; /* current node pointer in list */
newPtr = malloc(sizeof(Course)); /* memory allocation for new node */
if (newPtr != NULL) {
printf("Pls enter the code number of the course.\n");
scanf("%s", &(newPtr->code));
printf("Pls enter the course name.\n");
scanf("%s", &(newPtr->name));
printf("Pls enter the instructor name.\n");
scanf("%s", &(newPtr->instructor));
printf("Pls enter the term; Spring or Fall.\n");
scanf("%s", &(newPtr->term));
printf("Pls enter the year.\n");
scanf("%s", &(newPtr->year));
newPtr->coursePtr = NULL;
previousPtr = NULL;
currentPtr = *cr;
while ((currentPtr != NULL) && (code > currentPtr->code)) {
previousPtr = currentPtr;
currentPtr = currentPtr->coursePtr;
} /* End While */
if (previousPtr == NULL) {
newPtr->coursePtr = *cr;
*cr = newPtr;
} /* End if */
else {
previousPtr->coursePtr = newPtr;
newPtr->coursePtr = currentPtr;
} /* End else */
} /* End if */
else {
printf(" %c could not be inserted. Memory not enough...\n", code);
} /* End else */
} /* End function insert */
insertCourse(startPtr,字符*代码);它现在在“char”之前给出语法错误。 – Behzat
'insertCourse(&startPtr,course_code);' - 这个一定不能改变 – Alex
@Behzat,替换函数原型:'void insertCourse(CourseNodePtr * cr,Course code);'和函数定义与原型相同。 – Alex
