Not able to understand Compiler error

#include<stdio.h>

void swap(int& a,int& b)
{
int temp;
temp=a;
a=b;
b=temp;
}



void main()
{
int i=9,j=10;
swap (i,j);
printf (" i is %d",i);
printf (" j is %d",j);



}
Gives following compiler error
Error 1 error C2143: syntax error : missing ')' before '&'
Error 2 error C2143: syntax error : missing '{' before '&'

I am not able why compiler is complaining

Because C doesn't understand the C++ reference operator.

Unrelated to the error, do be polite enough to read and comply with the "How to Post..." thread before you get the hell flamed out of you.

And it's int main(), not void main().
