Why I got compilation error?!!!

Code: Select all

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
{
    char a[1000];
    while(scanf("%s",&a)==1)
    {
        if(a[0]=='\n' || a[1]=='\n')
        printf("\n");
        else
        printf("%s ",strrev(a));
    }
    return 0;
}

Where is my mistake, I cant find it.. MY code is here......
#include <stdio.h>
#include <string.h>

int main()
{
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;
}
}
printf("\n");
}
return 0;
}

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
ehT tuptuo lliw tsisnoc
fo eht emas senil dna sdrow sa eht tupni .elif

um getting PE ,,,, I/O is okk ... but PE ... plzzz help me.. m

Code: Select all

    code removed after AC

[sonjbond]

yaaa,, get AC now ...

[stride]

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.

[gr81]

sorry I didn't get your doubt....

[brianfry713]

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

[varrlo]

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

Code: Select all

AC

[brianfry713]

For input a.b output should be b.a

[varrlo]

So shall i just delete

Code: Select all

else if(lane[i] == '.')

? will it work?
nvm worked got AC
