填空题

[说明]
编写一个函数,输入为偶数时,调用函数求1/2+/+…+1/n,当输入n为奇数时,调用函数1/1+1/3+…+1/n (利用指针函数)。[函数]
#include "stdio. h",
main()
float peven (),podd (),dcall ();
float sum;
int n;
while (1)
scanf("%d",&n);
if (n>1)
break;
if(n%2==0)
printf("Even="):
(1);
else
pfinff("Odd=");
(2)
printf("%f",sum);
float peven (int n)
float s;
int i
s=1;
for(i=2;i<=n;i+=2)
(3)
return (s);
float podd (n)
int n;
float s;
int i;
s=0;
for(i=1 i<=n;i+=2)
(4)
return (s);
float dcall(fp,n)
float (*fp) ();
int n;float s;
(5)
returu (s);
