That was an attempt to answer to the following original question.
Are there some more "experts" on the field?
"Mình vừa gặp phải một lỗi rất khó hiểu. Đây là đoạn
mã nguồn của mình:
#include "stdio.h"
int main()
{
char str[80];
printf("Enter some words: ");
scanf("%s", str);
printf("The first word you entered is : %s\n", str );
printf("Enter some words: ");
scanf("%s", str);
printf("The first word you entered is : %s\n", str );
return 0;
}
và đây là kết quả mà mình mong đợi:
"Enter some words:hello word
The first word you entered is:hello
Enter some words:who are u?
The first word you entered is:who"
nhưng kết quả mà mình thu được lại là:
"Enter some words: hello word
The first word you entered is : hello
Enter some words: The first word you entered is : word"
Không thể hiểu nổi tại sao hàm scanf() lại chỉ hoạt động
đúng một lần. Ngay cả khi mình đã sử dụng hàm fflush(stdin)
nhưng kết quả vẫn như cũ. Ai đó giúp mình với. Mình xin
cám ơn!!!"
