To use words for a variable

Code:

---

//To use a persons name


#include<iostream.h>
main()
{

int a;
char c,
cout<<"Enter name"<<"\n";
cin>>c>>;
cin.get();
cout<<"age"<<"\n";
cin>>a;

if(a=xyz)
 {
    cout<<"abc"<<"\n";
cin.get();
}
return 0;
}

---

The problem is that i cannot use a=xyz. I am a good QBasic Programmer. In QBasic we use

10 x=asd THEN PRINT "afddafadad";
Is there something similar to this in C++?

std::string (which you would need to use #include <string> to make use of std::string) would be the right type for your variable. Obviously, xyz is not a string [in any sense]. You probably wanted to say

Code:

---

if (c == "xyz")

---

.

You should also avoid the old style <iostream.h> in preference of <iostream> - although you may find that the 10+ years old Turbo C is not suitable for modern C++ compiling, so you may need to update to a later compiler - there are free ones around, and suggestions for those if you search the forum - there's usually one or two suggestions of this per week.

Your code is invalid C++.

Code:

---

#include<iostream.h> // Deprecated header.
main() // ERROR: Missing explicit return type (should be int).
{
int a;
char c, // ERROR: Declaration does not end with ;
cout<<"Enter name"<<"\n";
cin>>c>>; // ERROR: Missing identifier after "c>>".
cin.get();
cout<<"age"<<"\n";
cin>>a;

// ERRORS:
// 1. a is a char, not a string.
// 2. = is assignment, not comparison.
// 3. xyz is interpreted as a variable, not a string.
if(a=xyz)
 {
    cout<<"abc"<<"\n";
cin.get();
}
return 0;
}

You need to go back to your books!

there. BTW thats not very good Qbasic either, but thats a topic for another board

Comparing a char to 'xyz'?

>> #include<iostream.h> // Deprecated header.

Note that <iostream.h> is not deprecated by the standard because it is completely non-standard. Deprecated implies that it is allowed but discouraged.

Expanding on what Elysia said, and what you changed once already...

Code:

---

//To use a persons name
 
 
#include<iostream.h>
main() //ERROR: still needs a return type
{
 
int a;
char c;
cout<<"Enter name"<<"\n";
cin>>c;  // removed the apparently unnecessary >>
cin.get();
cout<<"age"<<"\n";
cin>>a;
 
if(a=='xyz') //ERROR: wrong use of ' '
 {
    cout<<"abc"<<"\n";
    cin.get();
}
return 0;
}

Gah, you are right, its nto even comaprign a char to 'xyz' its comparing int to 'xyz', evene worse. Sorry, the air is ou tin our office and it's a bazillion degrees here
