这个程序哪里不对啊该怎么处理

这个程序哪里不对啊？
//输入年龄转化为秒
#include"stdio.h"
int main(void)
{
  int age;
double float year;
printf("Please intput your age:\n");
scanf("%d",&age);
year=age*3.156e7;
printf("Your age is %d or %es.\n"age,year);
return 0;
}

[解决办法]

C/C++ code

#include<stdio.h>int main(void){  int age;double  year;printf("Please intput your age:\n");scanf("%d",&age);year=age*3.156e7;printf("Your age is %d or %es.\n",age,year);return 0;}
