C-将字符串复制到链接列表变量中

Question

#define STRLEN 65

/*Create linked list */
struct node {
   char str[STRLEN];
   struct node *next;
};

newInput = malloc(sizeof(struct node));
strcpy(newStr, newInput->str);

I left the other parts of the code, but it doesnt seem to be copying the string into newInput->str.

The string accepted is only 64 bytes.

It's just blank when I print it out after the copy. Any clue why?

Answer 1

You have the arguments to strcpy reversed, the first argument is the destination, the second argument is the source. Try:

strcpy(newInput->str, newStr);

Answer 2

您将strcpy的参数颠倒了。

Answer 3

The first parameter of strcpy is the destination and the 2nd param is the source.

So

strcpy(newStr, newInput->str);

should be

strcpy(newInput->str,newStr);

Answer 4

Your destination and source are backwards:

strcpy(newStr, newInput->str);

should be

strcpy(newInput->str, newStr);
