Thank you very much for kindly help.
Now, it's still WA. Please, tell me where is the problem in my code. Here is my modified code.

Code: Select all

#include<stdio.h>
#include<string.h>
int main()
{

	while(true)
	{
	char s1[101]={'\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0'};
	char s2[101]={'\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0'};
		int max,len1,len2;
			gets(s1);
			len1=strlen(s1);
			if(s2[0]=='\0' && s1[0]!='\0')
			{
				gets(s2);
				len2=strlen(s2);
			}
			if(s2[0]=='\0' && s1[0]=='\0') break;
			if(len1>len2)
			{
					max=len1;
			}
			
			else if(len2>len1)
			{
					max=len2;
			}
			else
					max=len1;
					
					
			int fag=0;
			for(int i=0 ; i<max ; i++)
			{
				printf("%c%c\n",s2[i],s1[i]);
				//if(i<max-1) printf("\n");
				fag++;
			}

			if(fag!=0)
			{
					for(int i=0 ; i<max ; i++)
					{
							s2[0]='\0';
					}
			}

	}
	return 0;
}

You're still assuming there are always two sentences, there could be up to 100, each of length up to 100. You also can't print the null characters at the end of a line, those should be spaces.

Try this input at http://www.uvatoolkit.com/problemssolve.php
Sentence one.
Sentence two is longer.
Shorter.

freopen("490.txt","r",stdin);
char rot[L][R];
int n=0;
for(int i=0;i<100;i++)
for(int j=0;j<100;j++)
rot[j]='\0';
while(gets(rot[n]))
if(n<100)
n++;
for(int i=0;i<100;i++)
{
for(int j=0;j<n;j++)
if(rot[j]!='\0')
{
cout<<rot[j];
if(j==n-1)
cout<<endl;
}
else continue;
}
return 0;
}


and the 490.txt is:

Read the input from stdin, not a file.

}
else continue;
}

}

When I submit,i don't use "stdin" or "490.txt", i just use the codes above. But always i get Runtime Error,and i really don't understand.

Your problem might be that arr is uninitialized and then you check it for '\0'. On my machine (and possibly the judge's) that gave different results.

For your JAVA code, try the input:

Code: Select all

"I think, therefore I am."
Rene Decartes once said,
Output should be:

Code: Select all

R"
eI
n 
et
 h
Di
en
ck
a,
r 
tt
eh
se
 r
oe
nf
co
er
 e
s 
aI
i 
da
,m
 .
 "
There should be a newline at the end of the last line.

I'm having the same problem. I can't seem to see what's wrong with my output. Please help.

Code: Select all

#include <stdio.h>

int main(){
	char input[100][100] = {'\0'};
	int counter[100] = {0}; 
	char ch;
	int a = 0;
	int b = 0;
	int c = 0;
	int h;
	int i;
	int nos = 0; 
	int high = 0; 
	
	while (scanf ("%c", &ch) != EOF) {
		if (ch != '\n') {
			
			if (ch != '\t'){
				input[a][b] = ch;
				b++;
			}
			
		} else {
			counter[c] = b;
			
			if (high <= b) {
				high = b; 
			}
			
			c++;
			b = 0;
			a++;
			input[a][b] = ch;
		}
		nos = a;
		
	}
	
	a = nos - 1;

	for (h = 0;h < high;) {
		for (i = a; i >= 0; i--) {
			printf("%c", input[i][h]);
		}
		printf("\n");
		h++;
	}
	return 0;
}

For the sample input, you're printing null characters at the end of the last two lines.
