如何在C中收集尚未确定的性质?
原标题:How to collect a non-predetermined set of characters in C?

I have a textbook exercise right after looping and using char values (meaning that I can t use arrays and strings).

按照这一做法,我(用户)必须使用户进入一套果园。

例如,“IamaDinosaur”,然后发现该信的价值最高。

我如何选择<条码>scanf(),让用户进入<条码><>。 用户点击之前的数值? 那么,如何比较价值观?

最佳回答

如果你能够使用<代码>getch(>),那么,正如民间人士建议,你当然可以使用<代码>scanf(>,并且只是在扫描失败之前,或者读到一条新线:

char max = 0, here;
while(scanf("%c", &here) == 1 && here !=  
 )
    if(here > max)
        max = here;
printf("max= %c 
", max);
问题回答

您可以使用<条码>。

int ch;
int max = EOF;
while ((ch = getc(stdin)) != EOF && ch !=  
 )
    if (max < ch)
        max = ch;

很明显,你可以走<代码>scanf("%c”)路。
