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?

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);
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。
