打印的ASCII碼值，並用C

Question

它們的等效字符我怎麼能打印字符對於給定的ASCII碼值？..

我看到這個question，我的問題是相似的，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

在你的代碼，你必須改變你的printf語句

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); 

因爲，打印值，你並不需要提供地址的變量。變量名稱就夠了。

Answer 2

更改您的代碼：

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;}
