질문 제목 :c언어 복소수문제

질문 요약 :c언어 복소수를 다음과 같이 정의하고 복소수의 덧셈, 뺄셈, 곱셈, 나눗셈을 수행하는 함수를 작성하는 겁니다

struct tagcomplex
{
double real;
double image;
};

질문 내용 :
#include stdio.h
typedef struct tagcomplex
{
double real;
double image;
}complex;
complex addcomplex(complex a,complex b);
complex subcomplex(complex a,complex b);
void printfcomplex(complex a);
int main(void)
{
complex a,b,c;
a.real=1; b.image=2;
b.real=3; b.image=4;
printf(a:);
printcomplex(a);
printf(\nb:);
pirntfcomplex(b);
printf(\na+b:);
c = addcomplex(a, b);
printfcomplex(c);
printf(\na-b:);
c = subcomplex(a, b);
printfcomplex(c);
return 0;
}
complex addcomplex(complex a, complex b)
{
complex res;
res.real = a.real + b.real;
res.image = a.image + b.image;

return res;
}
complex subcomplex(complex a, complex b)
{
complex res;
res.real = a.real - b.real;
res.image = a.image - b.image;

return res;
}
void pirntcomplex(complex a)
{
printf(%lf+%lfi, a.real, a.image);
}에러가 4개가 뜨네요 ㅠㅠ 도와주세요~
