大家好,
我尝试使用链接列表准备学生信息系统。我创建了一个名为Course的脚本。用于插入过程;我将在函数main中调用void insertCourse(CourseNodePtr * cr,char *代码)。当我编译时,我看到这些错误。 “ insertCourse”的arg 2的类型不兼容。函数“ insertCourse”的参数太少。有人对此事发表评论吗?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 */
最佳答案
insertCourse的第二个参数期望类型为*char
,而您正在传递类型为Course
insertCourse(&startPtr, course_code);
