you can use gets to get one line and then tokenize it

ex :
[c]char line[100];
gets (line);

for (int i=0;line!='\0';i++)
if (line==' ') {
//if it's space do something....
}
else {
// do something else....
}
[/c]

another way is to use strtok.

just curious, are you trying to solve 494??

What do you mean \n? Is it special in any way?

I think the problem might be that I don't have the US keyboard, and the position of the keys are a bit mixed up.

Am I missing the numbers. I don't know, I can't see that the numbers must also be implemented.

qwaszx outputs {};`./
I found that this is correct (few pages back on this forums).

PS. Do I have to treat shift keys aswell? ([] instead of {} and so)?

About input.

Post by _.B._ »

Greetings!.
For this problem I considered only these characters, and the "space bar", as valid input:

Code: Select all

ertyuiop[]dfghjkl;'cvbnm,.
Hope it helps.

[c]
#include <stdio.h>

int main()
{
char a[100000];
char C[47]={"{}qwertyuiop[];

1. Change this:

Code: Select all

case '}':
      return 'p';
   case '{':
      return 'o';
for this:

Code: Select all

case ']':
      return 'p';
   case '[':
      return 'o';
2.Add this to function switch

Code: Select all

case ' ':
      return ' ';
Let my know you get AC
