char str[90000];
int i,j,t,len;
while(gets(str))
{
t=0;
len = strlen(str);
for(i=0;i<=len;i++)
{
if(str==' ' || i==len)
{
for(j=i-1;j>=t;j--) printf("%c",str[j]);
printf("%c",str);
t=i+1;

You're printing a null character at the end of each line. Don't use gets().
Use the existing thread for a problem. Use the code tags.

I have a question, what should happen if there is a space right before end of line ?? My code does not get the line feed for this. I did not used "gets".
At first got Wa. I read all the clarifications then Accepted. Some samples by my AC code.
Input:
Code: Select all
I love you.
You love me.
The output will consist
of the same lines and words as the input file.
However, the letters within each word must be reversed.
Output:
Code: Select all
I evol .uoy
uoY evol .em

i presume all my outputs are right, am i printing something invisible to the naked eye here? coz i got WA with this code..
Code: Select all
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<iostream>
using namespace std;
int main()
{
char string[9999];
char out[9999];
int j=0,k=0;
int length;
while(scanf("\n%[^\n]",&string)!=EOF)
{
length = strlen(string);
for(int i=0;i<length;i++)
{
if(string[i]==' ')
{
j=i-1;
while(string[j]!=' ' && j>=0)
{
out[k] = string[j];
j--;k++;
}
out[k] = ' ';
k++;
}
else if(i == length-1)
{
j = length - 1;
while(string[j]!=' ')
{
out[k] = string[j];
j--;k++;
}
}
}
cout<<out<<endl;
k=0;
}
return 0;
}

Try the I/O gba356 posted in this thread. Your code ignores spaces at the beginning of a line.

getting WA...please have a look...
#include <iostream>
#include <vector>
#include <string>
#include <string.h>
#include <ctype.h>
#include <stdio.h>
using namespace std;
void reverse(char *str, int start, int end)
{
if( start < end )
{
char tmp = str[start];
str[start] = str[end];
str[end] = tmp;
reverse(str, ++start, --end);
}
}
void process(char *str)
{
int len = strlen(str);
int start, end;
start = end = 0;
bool in_word = false;
int wc = 0;
for(int i=0; i <= len; ++i)
{
if( isalpha(str))
{
if(!in_word)
{
in_word = true;
start = i;
}
}
else if( (str == ' ') || (str == '\n') || (str == '\0'))
{
if(in_word)
{
in_word = false;
end = i-1;
reverse(str, start, end);
wc++;
}
}
}
}
int main()
{
vector<string> vs;
char str[90000] = {0};
while( scanf("%[^\n]", &str) != EOF)
{
getchar();
string lstr(str);
vs.push_back(lstr);
process((char*)lstr.c_str());
lstr.clear();
memset(&str, 0, sizeof(str));
}
vector<string>::iterator it;
for(it=vs.begin(); it != vs.end(); ++it)
{
cout << *it << endl;
}
return 0;
}
Thanks in Advance.

Try updating your code to not print a newline at the end of a line if EOF is reached.

For input "asdf\n" the output should be "fsda\n".
For input "asdf", the output should be "fdsa", your code prints "fdsa\n".

Well I got WA and I have no idea what is the problem. Is it because of new line in the end of output?
