C++ Question

I'm solving this problem and I am stuck on the two other if comditionsI have. I'm not sure how to check from **b to g** or **2-7**. I'm also confused on how to check if all 8 spots are available. I always get confused when iterating or checking code with if and for loops. Here is what I have so far:

Problem:

http://codeforces.com/problemset/problem/710/a

Code so far:

`#include <iostream>`

#include <string>

using namespace std;

int main(){

string c;

cin >> c;

if(c == "a8" || c == "h8" || c == "a1" || c == h1){

cout << "3 moves only available\n" << endl;

}

// confused on this case

if(c == c[0]( ){

cout << "5 moves only available\n" << endl;

}

// and this case

if(c ==){

cout << "all 8 moves are available\n" << endl;

}

}

First of all, `h1`

should be in inverted commas as it is a string literal, should look like this instead `"h1"`

.

Second, the case when there are only 5 moves are along the side of the board (but not corners). Thus you only need check if the file (column) is `'a'`

or `'h'`

or if the rank (row) is `'1'`

or `'8'`

. Use `else if`

to shortened to code so that you don't output twice if it is a corner.

So your second case can look like this:

```
else if (c[0] == 'a' || c[0] == 'h' || c[1] == '1' || c[1] == '8){
cout << "5 moves only available\n" << endl;
}
```

The last case is just:

```
else{
cout << "all 8 moves only available\n" << endl;
}
```

as all other cases have been dealt with
