扫描到新行 [英] Scanning until new line

问题描述

我想阅读所有输入的文本，直到输入新的行字符.

I want to read all the text entered until a new line character is entered.

这是我的代码.

int i=0;
char ch[MAX];
printf("Enter the text\n");
while(true)
{
     scanf("%c",&ch[i]);
     if(ch[i]=='\n')
         break;
     i++;
}

但是当我尝试执行时，它只读取一个字.

But when I try to execute it reads only one word.

我也试过 scanf("%s",ch); 但结果是一样的.

I have also tried scanf("%s",ch); but the result is the same.

推荐答案

在依赖 ch[i] 之前，您没有检查 scanf() 是否成功一个有效的值，这不是一个好主意.

You're not checking that scanf() succeeds before relying on ch[i] to have a valid value, that's not a good idea.

只需使用 fgets() 即可阅读全文立即排队.

Just use fgets() to read a whole line at once.
