error C2665: 'add' : none of the 2 overloads can convert parameter 1 from type 'struct plura'

#include<iostream>
using namespace std;
struct plura
{
float complex;
float imaginaryPart;

void add(int n,int i,int &sum);
void add(struct plura n,struct pluar i,struct plura & sum);

Answer 1

void add(struct plura n,struct plura i,struct plura & sum);
注意拼写。

Answer 2

//compiled by g++
#include<iostream>
#include<conio.h>

using namespace std ;
void witch( int * ,int*);
void witch( double ** , double ** );
void show(double []);
int main()
{ int A =1 , B=2 ;
double C[2]=;
double D[2]=;
double *pt1=C,*pt2=D; //amend here

cout<<A<<" "<<B<<endl ;
show(C);
show(D);
witch(&A,&B);
witch(&pt1,&pt2);
cout<<A<<" "<<B<<endl ;
show(pt1); //amend
show(pt2); //amend
getch();
return 0;}
void witch ( int *m,int *n )
{ int L;
L=*m ;
*m=*n;
*n=L;
return ; }

void witch ( double **M , double **W )
{ double *p ;
p=*M;
*M=*W;
*W=p;
return ;}

void show(double X[])
{for(int i=0;i<2;i++)
cout<<X[i]<<" ";
cout<<endl;
return ;}

追问

请问您能解释我的那个问题么？？错误在哪里？？错误是什么意思？？该如何改正？谢了！！！
