#include<stdio.h>

int Fibonacci(int 2)

{
	if(1==0)

		return 0;

	else if(1==1)

		return 1;

	else

		return (Fibonacci(2-1)+Fibonacci(2-2));
}

void main()
{
	int end,i;

	printf("Enter>");
	scanf("%d",&end);

	for(i=1;i<end;i++)

		printf("%d",Fibonacci(i));

	printf("\n");
}

I have three errors:

C:\Users\jian\Desktop\Cpp1.cpp(4) : error C2143: syntax error : missing ')' before 'constant'
C:\Users\jian\Desktop\Cpp1.cpp(4) : error C2143: syntax error : missing ';' before 'constant'
C:\Users\jian\Desktop\Cpp1.cpp(4) : fatal error C1004: unexpected end of file found

But I do not know what they mean. Pls help.

I doubt that the file you posted is the same file you are compiling, or perhaps you have some strange character that the compiler does not recognize (perhaps if you are using a rich text editor)

When fixing compiler errors, always start with the first one, as fixing that often fixes subsequent errors. Then, read up on the rules for C identifiers. Look at the parameter list for your Fibonacci function. Notice anything wrong with it?

Also, your if statements are bogus. They never take into account the parameter you pass in. The first one is always false (one is never equal to zero), so it will be skipped. The second one is always true, so your function will always return one, and the last one also never gets executed.

A couple other things to fix:
It's int main(void) and return 0 when you're done
Put some spaces or a newline between the numbers you print out so we can tell what's going on.

Duh. Missed that one.

You can't define a variable name by a number. 2 is not a valid variable name.

And even if it was, what would possess you to do it?!

I got it now, all I have to do is change the numbers to 'n'. Somehow I got confused along the way.
