c++问题 关于结构error: expected primary-expression before '{' token

帮帮忙吧，初学者，可这个程序总也编译不了，自学真麻烦呀
#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
int number(0);
double number1(0);
double number2(0);
struct Convert
{
char convert_name[100];
double convert_rate;
};
Convert convert[3];
convert[0]={"yuan to dollar",0.125};
convert[1]={"dollar to pound",2};
convert[2]={"yuan to pound",0.0625};
cout<<"choose a way to convert money"<<endl<<"1.yuan to dollar"<<endl<<"2.dollar to pound"<<endl<<"3.yuan to pound";
cin>>number;
cout<<"please enter the type that you want to convert";
cin>>number1;
if(number<3&&number>=0)
number2=number1*convert[number-1].couvert_rate;
else
cout<<"sorry ,you entered a wrong number";
cout<<number1<<convert[number-1].convert_name<<" is "<<number2;

system("PAUSE");
return EXIT_SUCCESS;
}
下面是错误信息

如下：

#include <cstdlib>

#include <iostream>

using namespace std;

int main(int argc, char *argv[])

{

int number(0);

double number1(0);

double number2(0);

struct Convert

{

char convert_name[100];

double convert_rate;

};

Convert convert[3] = {{{"yuan to dollar"},0.125},{"dollar to pound",2},{"yuan to

pound",0.0625}};

cout<<"choose a way to convert money"<<endl<<"1.yuan to dollar"<<endl<<"2.dollar to

pound"<<endl<<"3.yuan to pound";

cin>>number;

cout<<"please enter the type that you want to convert";

cin>>number1;

if(number<3&&number>=0)

number2=number1*convert[number-1].convert_rate;

else

cout<<"sorry ,you entered a wrong number";

cout<<number1<<convert[number-1].convert_name<<" is "<<number2;

system("PAUSE");

return EXIT_SUCCESS;

}
