打印的ASCII码值，并用C

Question

它们的等效字符我怎么能打印字符对于给定的ASCII码值？..

我看到这个question，我的问题是相似的，只是相反

下面是我的程序，但它不起作用。

int main(){ 
int code;  // code that user enters 
char ch;  //"codes" related ASCII charcter 

printf("Enter a ASCII code value: \n"); 
scanf("%d", &code); 
ch=code; 

printf(" %c is cherechter that have %d ASCII code\n", &ch ,&code); 

system("PAUSE"); 
return 0;} 

Answer 1

在你的代码，你必须改变你的printf语句

printf(" %c is cherechter that have %d ASCII code\n", &ch ,&code); 

到

printf(" %c is cherechter that have %d ASCII code\n", ch ,code); 

因为，打印值，你并不需要提供地址的变量。变量名称就够了。

Answer 2

更改您的代码：

int main(){ 
char code; //change from int to char 
char ch;  

printf("Enter a ASCII code value: \n"); 
scanf("%c", &code);//ASCII is a character not integer 
ch=code; 

printf(" %c is cherechter that have %x and %d ASCII code\n", ch ,code,code);//don't print the address access the value 

system("PAUSE"); 
return 0;}
