Hello Everyone I'm learning to code in dev c++ 4.9.8.0 version 2

Hello Everyone I'm learning to code in dev c++ 4.9.8.0 version 2

Here is the code Simple as it is

Code:

---

#include <stdio.h>
main()
{
Printf ( " My first program in Dev c++.\n");
return 0;
}

---

And it doesnt work can anyone help?

Also I would like to get any helpful links to help a new beginner

Thankyou Eric

Code:

---

#include <stdio.h>
int main()
{
Printf ("My first program in Dev c++.\n");
return 0;
}

---

u forgot the to add the "int" in front of the main()

That's C code, for C++ do this:

Code:

---

#include <iostream>
using namespace std;

int main(void)
{
cout<<"Hello World!"; //C++ for printf()

}

---

youd also want to change "printf" into "cout <<" if ur doing c++

ohh no wonder i was like what is this printf i was about to tell him about the cout etc.. but then i didnt know for sure

Code:

---

#include <iostream>
using namespace std;

int main(void)
{
cout<<"Hello World!"; //C++ for printf()

}

---

what is that void doing there.. i know voids there because of using namespace std; but why is it there??


this is what i would use to print out my first program..blah blah is:

Code:

---

#include <iostream.h>
int main()
{
cout << "My first program in Dev c++.\n";
return 0;
}

---

hope that works :)

void doesn't need to be there at all, I just like to put it there when I'm not using command line arguments (int argc,char* argv[])

It was necessary in C though, wasn't it (to put void there)?

I don't know C...

yes.

In C++ int main() is int main(void)
In C, int main() is int main(..)

In C++ isn't it still correct if you do this:

Code:

---

#include <iostream>
using namespace std;

main (void)
{
    cout << "Blah";
}

---

rather than this:

Code:

---

#include <iostream>
using namespace std;

int main (void)
{
    cout << "Blah";
    return 0;
}

---

nahhh

gotta tell yo prog the function

gotta be:

Code:

---

#include <iostream>
using namespace std;

int main (void)
{
    cout << "Blah";
    return 0;
}

---

Actually, this should also compile fine as C++, but not C:

Code:

---

int main( void ) {
}

---

It compiled fine without the int too, in Dev-C++...

This might prove useful.

It compiles fine because in C++ if you don't specify a data type for a function it defaults to int.
