while ()这是啥，这东西能编译，不报错？
case里void shourujilu();这是函数声明，不是函数调用
把声明放到main函数的前面去，case里的void都删掉
有两处代码有问题。
# 在case语句中调用函数时,漏掉了函数名称和参数:
case 1:
void shourujilu();
break;
# 应该写为:
c
case 1:
shourujilu();
break;
# 在定义函数原型时,漏掉了参数列表:
c
void shourujilu()
# 应该写为:
c
void shourujilu();

用递归的方法，当n=10天时，返回int n=1；
#include <stdio.h>
int getPeachNumber(int n) //这里要定义n，要不编译器会报错！
{
int num;
if(n==10)
{
return 1;
}
else
{

printf("第%d天所剩桃子%d个\n", n, num);
}
return num;
}
int main()
{
int num = getPeachNumber(1);
printf("猴子第一天摘了:%d个桃子。\n", num);

}运行结果：
第9天所剩桃子4个
第8天所剩桃子10个
第7天所剩桃子22个
