Ignoring the Space

closed account (21vXjE8b)
Yeah, I'm back with another question.
My code works like this: You write a message (heLLo), choose a key value (e.g. 3) and the result is khOOr (3 letters forward, with lower or upper case!).
The problem, is that if you write "Hello World" (with key value = 3), it will print "Khoor#Zruog". That means the space was considered in the code and was codified. I wanna ignore it, but maintaining he in the final.

Original code:

1

3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
 
 string msg_E;
    char result_E, i;
     int i;

	for (i=0; i < msg_E.length(); i++) {
			result_E = msg_E[i] + keyValue_E;
			
			if (isupper(msg_E[i])) {
				if (result_E > 90) result_E -= 26;
			}
		
			if (islower(msg_E[i])) {
				if (result_E > 122) result_E -= 26;
			}
			
			cout << result_E;
		}



I tried to restrict the ASCII characters, but it didn't work.
*In here, even if result_E = msg_E[i] + keyValue_E; is inside or before the If statements, the space continue being considered.

for (i=0; i < msg_E.length(); i++) {
			result_E = msg_E[i] + keyValue_E;
		
			if (msg_E[i] >= 65 && msg_E[i] <= 90) {
				if (result_E > 90) result_E -= 26;
			}
			
			if (msg_E[i] >= 97 && msg_E[i] <= 122) {
				if (result_E > 122) result_E -= 26;

                        cout << result_E;
			}


And I tried to consider only alphabetic characters, but it suppress the space in the end.

     for (i=0; i < msg_E.length(); i++) {

          result_E = msg_E[i] + keyValue_E;

          if (isalpha(msg_E[i])) {
			
			
			if (isupper(msg_E[i])) {
				if (result_E > 90) result_E -= 26;
			}
		
			if (islower(msg_E[i])) {
				if (result_E > 122) result_E -= 26;
			}
			
			cout << result_E;
		        }
		}

Hi,

What didn't work?

The space continue being considered.

So you want to keep the space or you want to remove the space?

Didn't work... =/
It suppressed the space in the result.

It suppressed the space in the result.

What do you mean by that? What happened to the previous statement of yours?

Sorry, I wasn't clear... :S
In the original code, if I enter "Hello World", it prints "Khoor#Zruog".
With the isspace, if I enter "Hello World", it prints "KhoorZruog".
I want it to prints "Khoor Zruog".

I assume you meant this?

for (i=0; i < msg_E.length(); i++)
{
     if(isspace(msg_E[i])) {cout << msg_E[i]; continue;}
