Undefined reference to function

[gm17]

hi,i try to send an array to a function but i got some error messages like
222.cpp:(.text+0x2b): undefined reference to `function(int, int*)'
C:\Users\***\Desktop\collect2.exe [Error] ld returned 1 exit status
what can i do?

void fuction(int a,int *b){  	
}
int main()
{   
void function(int ,int * );
int x=20;
int array[20];

function(x,array);
}

That's not quite how functions work.

Check your spelling?

This is not the exact question. This is a very simple form of my program.
It returns an error. I have a long code and it returns same message as this one.

I think this line " void fuction(int a,int *b) " has a problem but I can't figure it out.

Small form of program or not, it's completely wrong.

void fuction(int a,int *b) // Function is misspelled, and empty. 

void function(int ,int * ); Why is this inside of main, what purpose does it have?
