打印“标签” [英] Printing "tab"
问题描述
我写了一个小小的无关紧要的程序，帮我写一个更多的
重要的!!这应该打印所有的Ascii值从0
到127：
#include< stdio.h>
#define UPPER_LIMT 127
int main（）{
int i;
printf（"％7s％7s \ n \ n"，Decimal，Value）;
for（i = 0; i< = UPPER_LIMT; i ++）
printf（"％3d％7c \ n"，i，i）;
返回0;
}
但是，我想看看，例如''TAB''而不是
颠倒问号，十进制值''9'。我可以在printf中使用
转换吗？
提前致谢。

提示：考虑一下接受char作为输入并返回
字符指针的函数。

字符指针。
oh哦......我在K& R的第77页......迫不及待地想要进入第93页
Pointers and Arrays!!!但是，如果你改变你的提示以避免
指针...我会字节:-)

哦哦....我在K& R的第77页...迫不及待地想要进入第93页
指针和阵列！ ！但是，如果你改变你的提示以避免
指针...我将字节： - ）
然后使用switch或if语句。
if（x ==''\ t''）printf（" tab"）;
else printf（"％c"，x）;
.....
看，妈，没想到！

I wrote a little insignificant program, to help me write a more
significant one!!...that was supposed to print all Ascii values from 0
to 127:
#include <stdio.h>
# define UPPER_LIMT 127
int main (){
int i;
printf("%7s%7s\n\n", "Decimal", "Value");
for ( i=0; i<= UPPER_LIMT; i++)
printf( "%3d%7c\n", i, i);
return 0;
}
However, I would like to see, for example, ''TAB'' instead of an
upside-down question mark, at decimal value ''9''. Is there a
conversion I could use for this in printf?
Thanks in advance.

Homework.
Hint: consider a function which accepts a char as input and returns a
char pointer.

oh oh....I am on page 77 of K&R...can''t wait to get to page 93
"Pointers and Arrays"!!! But, if you change your hint to avoid
pointers...I will byte :-)

Use a switch or if statement then.
if (x == ''\t'') printf("tab");
else printf("%c", x);
.....
Look ma, no thought!
