不提供正确的输出？ [英] Don't give correct output?

问题描述

程序应该接受单词aba和所有长度均匀的单词，例如abababb它应该给出有效的答案，但它不给出....

这是代码：

The program should accept the words aba and all words of even length such as abababb it should give valid answer but it is not giving....
Here is the code:

#include<conio.h>
#include<conio.h>
#include<stdio.h>
#include<string.h>
void main(void)
{
clrscr();
int i=0;
char str[30];
printf("Enter the input string: ");
gets(str);
if(str[i]=='a')
{
str[i++];
if(str[i]=='b')
{
str[i++];
if(str[i]=='a')
{
str[i++];
if(str[i]==NULL)
{
printf("\nVALID");
}
else
{
loop:
;
if(str[i]=='a'|| str[i]=='b')
{
str[i++];
goto loop;
}
else
{
goto a;
}
a:
;
if(i%2==0)
{
printf("\nVALID");
}
else
{
printf("\nINVALID");
}
}
}
else
{
printf("\nINVALID");
}
}
else
{
printf("\nINVALID");
}
}
else
{
printf("\nINVALID");
}
getch();
}


Please correct my code??</string.h></stdio.h></conio.h>

推荐答案

一个错误是：

one bug is:

str[i++];
//its is enough
i++;

错误是

the bug is

if(i%2==0)

abababb
，因为它不均匀。



考虑改进你的代码风格。真的：疯了：

for abababb, coz its uneven.

Consider improving your codestyle. Really :mad:
