在C中打印字符及其ASCII码

Question

如何在C中打印char及其等效的ASCII值？

Answer 1

这将打印出所有ASCII值:

int main()
{
    int i;
    i=0;
    do
    {
        printf("%d %c \n",i,i);
        i++;
    }
    while(i<=255);
    return 0;
}

这会打印出给定字符的ASCII值:

int main()
{
    int e;
    char ch;
    clrscr();
    printf("\n Enter a character : ");
    scanf("%c",&ch);
    e=ch;
    printf("\n The ASCII value of the character is : %d",e);
    getch();
    return 0;
}

Answer 2

尝试这个：

char c = 'a'; // or whatever your character is
printf("%c %d", c, c);

%c 是单个字符的格式字符串，%d 是数字/整数。通过将 char 转换为整数，您将获得 ascii 值。
