Hi every one, I am Blake.

I use to do a lot of programming on VB6 when I was younger but I'm only new to C++ and I can't figure out why this program to make a simple sentence does not work. ( works perfectly with numbers.)

Quote:

#include <iostream>

using namespace std;

main (void)

{

/* Values */
int a;
int b;
int c;
int d;
int e;

/* Some Sentences */
cout << " This is a program to write on your own sentences." << endl;
cout << " Write in your first word." << endl;

/* Input/Output */
cin >> a ;
cout << "" << endl;
cout << " Write in your second word." << endl;
cin >> b ;
cout << "" << endl;
cout << " Write in your third word." << endl;
cin >> c ;
cout << "" << endl;
cout << " Write in your fouth word." << endl;
cin >> d ;
cout << "" << endl;
cout << " Write in your fith word." << endl;
cin >> e ;
cout << "" << endl;
cout << "" << endl;

/* The Maths */
cout << a+b+c+d+e << endl;

/* System Commands */
system ("PAUSE");

}

Any help?

Blake;

You need to use string instead of int if you're going to store letters.

Thank you;

Now I just need to fix the spaces problem:

Quote:

#include <iostream>

using namespace std;

main (void)

{

/* Values */
string a;
string b;
string c;
string d;
string e;

/* Some Sentences */
cout << " This is a program to write on your own sentences." << endl;
cout << " Write in your first word." << endl;

/* Input/Output */
cin >> a ;
cout << "" << endl;
cout << " Write in your second word." << endl;
cin >> b ;
cout << "" << endl;
cout << " Write in your third word." << endl;
cin >> c ;
cout << "" << endl;
cout << " Write in your fouth word." << endl;
cin >> d ;
cout << "" << endl;
cout << " Write in your fith word." << endl;
cin >> e ;
cout << "" << endl;
cout << "" << endl;

/* The Maths */
cout << a+b+c+d+e << endl;

/* System Commands */
system ("PAUSE");

}

Spaces? If you mean space between output between the variables, it can be fixed by changing:

Quote:

cout << a+b+c+d+e << endl;

Quote:

cout << a << " " << b << " " << c << " " << d << " " << e << endl;

And do not use + ever as a means to build output. Even in VB6 it can cause integers to be added up and you end up with a sum instead of an output. You can always process values as character variables by typecasting them implicitly with (char) in C/C++ or (string) in C#/Java or CStr() for VB.NET, or using the .toString() method after a variable in both Java and .Net languages.

Regardless of language, the best thing to do is to use a stringbuilder class when you build a textstructure that is going to be presented to the user.

Okey, Thank you.

I'm not sure if I understood all of that, but thank you.
