Object Oriented programing
Lets see conventional way of C++ to do some things.
#include
class string
{
char str[20];
public:
string();
void operator+(string &);
void operator>>(istream &);
void operator<<(ostream &);
};
string::string()
{
}
void string::operator + (string &s)
{
cout << strcat (str,s.str);
}
void string::operator>>(istream &din)
{
din>>str;
}
void string::operator<<(ostream &dout)
{
dout<str;
}
void main()
{
string s1,s2;
cout <<"Please enter a string"<
cout <<"Please enter second string"<
s1+s2;
}
Now for some Ruby work
#!/usr/bin/ruby
a='harshad'
b='joshi'
c=a+b
print"c"
Job over. Isent Ruby more cool??
Why do Indian engineering institutes and colleges prefer more of C++, when many good options are available?

If the work involves just concatenation of two strings then any of ruby, shell, perl, python scripts could be used. But in real industry the work is much more than concatenating 2 strings. If you're part of the industry already you wouldn't have posted this blog, if you're not you'll learn sooner or later. You could use java instead of c++ if you wish.
Is this joke?
#include <iostream>
#include <string>
int main() {
std::string a = "John";
std::string b = "Doe";
std::cout << a << b << std::endl;
return 0;
}
I agree Ruby is cool. Scripting languages are not scalable when used as part of the embedded systems (atleast not for now). They have their own overheads.
