Can anyone help with my code?
It's such a simple question and I keep getting wrong answer.
It is really frustrating.

I think you are printing an additional character when you reach the end of file.
Try putting the input in a file and read if from there. You should be able to see the error.

I've just compiled and runned your code and turns out that it works fine in my box.
I even compared your output against my AC'd code's output and they are identical.
Have you searched for any additional input/output to test your code with?

Code: Select all

#include<stdio.h>
int main()
{
    char ch;
    int i=0;
    while(ch=getc(stdin)!=EOF)
    {
         if((int)ch==34)
         {
                        if (i==0)
                        {

                        }
         }
         else printf("%c",ch);
    }
    return 0;
}

The operators = and != have got the same precedence, however they are right associative.

That means ch = getc(stdin) != EOF is treated as ch = ( getc(stdin) != EOF ) and thus ch will always be assigned with a boolean (0/1) value.
You can get around this problem by enclosing the first two terms with parenthesis, something like ( ch = getc(stdin) ) != EOF

Hope it helps.

Hi guys! What is the wrong of this code?

Code: Select all

#include <iostream>
#include <cstring>
#include <string>

using namespace std;

string s;

void Shift(int i){
	s += s[s.length() - 1];
	for (int j = s.length() - 2; j > i; j--)
		s[j + 1] = s[j];
}

int main(){
	while (getline(cin, s))
	{
		if (s.length() > 0)
		{
			int j = 0;
			int b = s.length();
			int z = 0;
			int ord = 39;
			for (int i = 0; i < b; i++)
			{
				int a = s[i + z];
				if (a == 34)
				{
					j++;
					if (j % 2 == 1)
					{
						s[i + z] = '`';
						Shift(i + z);
						s[i + z + 1] = '`';
						z++;
					}
					else
					{
						s[i + z] = ord;
						Shift(i + z);
						s[i + z + 1] = ord;
						z++;
					}
				}
			}
			cout << s << endl;
		}
	}
}

kia.masster I can see you already figured out that you weren't closing the quotes correctly across multiple lines.

one another thing...if input is [this"]
then would the last " be replaced by `` or ' ' ??

Run your code and do a diff against the sample I/O. It doesn't match line 2.
