复数乘法* 下面的程序输入两个复数(实部、虚部)，相乘后输出乘积。请在空白处填写适当内容完成该程序。 #include <stdio.h> typedef struct { double rp, ip; } COMPLEX; void Input(COMPLEX *p); void Output(const COMPLEX *p); COMPLEX Multiply(COMPLEX *p, COMPLEX *q); int main() { COMPLEX a, b, c; Input(&a); Input(&b); c = ; Output(&c); return 0; } void Input(COMPLEX *p) { scanf("%lg %lg", ); } void Output(const COMPLEX *p) { printf("%g %g", ); } COMPLEX Multiply(COMPLEX *p, COMPLEX *q) { COMPLEX r; r.rp = ; r.ip = ; return r; }

# include <stdio.h>
typedef struct {
double rp, ip;

void Input(COMPLEX *p);
void Output(const COMPLEX *p);
COMPLEX Multiply(COMPLEX *p, COMPLEX *q);

int main() {

Output(&c);
return 0;
}

void Input(COMPLEX *p) {
scanf("%lg %lg", &p->rp, &p->ip);

r.ip = p->rp * q->ip + p->ip * q->rp;
