Why judge still give me a WA instead of a AC
here is my code:
Code: Select all
#include <iostream>
#include <string>
using namespace std;
string word;
char ch;
void reverseOut(string &s)
{
long i=s.length()-1;
while(i>=0)
{
cout<<s[i];
i--;
}
}
void main()
{
while(cin.get(ch))
{
if(ch==' '||ch=='\n')
{
reverseOut(word);
cout<<ch;
word="";
}
else
{
word+=ch;
}
}
}
Waiting your help!!![/code]
your code can`t process last input.
if last input doesn`t have ' 'or '\n',
the output must be wrong.
Code: Select all
void main()
{
while(cin.get(ch))
{
if(ch==' '||ch=='\n')
{
reverseOut(word);
cout<<ch;
word="";
}
else
{
word+=ch;
}
}
reverseOUt(word);//<----I think that you loss this.
}

Why this is getting WA??I cant find the bugs
Code: Select all
#include<stdio.h>
#include<string.h>
void reverse(char *s){
int i,j,c;
for(i = 0,j = strlen(s)-1;i<j;i++,j--){
c = s[i];
s[i] = s[j];
s[j] = c;
}
}
void main(){
int c,i = 0,flag = 0;
char arr[500];
while((c = getchar())!=EOF){
if(c == '\n'){
if(flag == 0)
printf("\n");
else{
arr[i] = '\0';
reverse(arr);
printf("%s\n",arr);
}
i = 0;
continue;
}
flag = 1;
if(c != ' ' && c!='\t'){
arr[i] = (char)c;
i++;
}
else{
arr[i] = '\0';
reverse(arr);
printf("%s%c",arr,c);
i = 0;
flag = 0;
}
}
}

You have to process the last word....
You do it only when the last word is followed by a '\n' or ' '.....
but not for the word immediately followed by EOF..
Good luck!

Just make a input file with the following input set...
Input:
Then match the output set.
Output:
But your code enters into an infinity loop. Try to take input with gets().
Hope it helps.

But it can run in my computer!
strange......

Actually when I used the inputs manually it returns the output but, when I made a file and ran the code using that input file it returns nothing but an infinity loop...

I change it to gets
but when it print ctrl+Z
How can I know it and return 0 ?

gets() returns NULL (0) on EOF (ctrl+z). So it should be simply
Code: Select all
char a[1000];
while( gets(a) ){
..........
}

I think you have to delete some words.
Are you think too?
