怎样定义一个字符类型的宏在双引号中可以使用

[stormier]

#define ABC 'p'这样肯定不行

虽然没看懂你的需求 但是，宏不是万能的，别什么东西都想扯到宏来实现。 基本上，是你的需求错误。

#include <stdio.h>
#define BUF_LEN 1024
#define EMAIL_LEN 80
#define QUOTE1(q) #q
#define QUOTE(q) QUOTE1(q)
char s[]="\"单身\"<[e-mail]>; \"XXD\"<[e-mail]>; \"凤凰\"<[e-mail]>;\"\" <[e-mail]>;\"\" <[e-mail]>;\"\" <[e-mail]>;";
char *p,*q;
int n,k;
char e[EMAIL_LEN];
char b[BUF_LEN];
void main() {
    p=s;
    q=b;
    while (1) {
        if (1==sscanf(p,"%*[^<]<%"QUOTE(EMAIL_LEN)"[^>]>%n",e,&n)) {
            p+=n;
            k=sprintf(q,"%s|",e);
            q+=k;
            if (q-b>BUF_LEN-EMAIL_LEN) break;
        } else break;
    }
    q[-1]=0;//去掉末尾的|
    printf("%s\n",b);
}
//[e-mail]|[e-mail]|[e-mail]|[e-mail]|[e-mail]|[e-mail]
