[Quote=引用楼主 enight0000 的回复:]
C/C++ code
#include <stdio.h>
#include <stdlib.h>
#define N 100

char Check(char m);
char Trans(char n);
char TransR(char n);
int main()
{
char DNA[N];
char DNAX[N];
int i;

printf("请……
[/Quote]
for(i=0;DNA[i]!='\0',i++) 改为 for(i=0;DNA[i]!='\0';i++)
三个for循环的第二个逗号改为分号

[自信男孩]

1. printf("/n输入的DNA单链为: -");2. printf("/n");
应该是： printf("\n");
