int main() {
    char a[100];

    printf("\nEnter 1st Sentence : ");
    scanf("%[^\n]", a);
    printf("\nSentence 1 : %s", a);

    printf("\nEnter 2nd Sentence : ");
    scanf("%[^\n]", a);
    printf("\nSentence 2 : %s", a);

    return 0;
}

我的输出：

Enter 1st Sentence : Testing 1st Sentence
Sentence 1 : Testing 1st Sentence
Enter 2nd Sentence : 
Sentence 2 : Testing 1st Sentence

我基本上是在检查%[^\n]。当我输入第一个句子并按“Enter”键时，它会打印“Enter 2nd Sentence :”，然后打印“Sentence 2 :”，然后打印第一个句子。
