一道觉得很简单的编程题，提交了很多次，但是，还是wrong，实在是崩溃啊，真的不知道哪里错了，希望大家可以帮忙解决一下，感激不尽。

Description

Conversion between the metric and English measurement systems is relatively simple. Often, it involves either multiplying or dividing by a constant. You must write a program that converts between the following units:

 Type Metric English equivalent Weight 1.000 kilograms 2.2046 pounds Weight 0.4536 kilograms 1.0000 pound Volume 1.0000 liter 0.2642 gallons Volume 3.7854 liters 1.0000 gallon

Input

The first line of input contains a single integer N, (1 <= N <= 1000) which is the number of datasets that follow.

Each dataset consists of a single line of input containing a floating point (double precision) number, a space and the unit specification for the measurement to be converted. The unit specification is one of kg, lb, l, or g referring to kilograms, pounds, liters and gallons respectively.

Output

For each dataset, you should generate one line of output with the following values: The dataset number as a decimal integer (start counting at one), a space, and the appropriately converted value rounded to 4 decimal places, a space and the unit specification for the converted value.

Sample Input

5
1 kg
2 l
7 lb
3.5 g
0 l

Sample Output

1 2.2046 lb
2 0.5284 g
3 3.1752 kg
4 13.2489 l
5 0.0000 g
下面是我的代码，求帮忙
```#include<stdio.h>
#include <string.h>
int main()
{
int n, i, count;
char a[1001];
double result, x;
while(~scanf("%d", &n))
{
for(i=0;i<n;i++)
{
scanf("%lf %s", &x, a);
if(strcmp(a, "kg")==0)
{
result=2.2046*x;
printf("%d %.4f lb\n", i+1, result);
}
else if(strcmp(a, "lb")==0)
{
result=0.4536*x;
printf("%d %.4f kg\n", i+1, result);
}
else if(strcmp(a, "l")==0)
{
result=0.2642*x;
printf("%d %.4f g\n", i+1, result);
}
else if(strcmp(a, "g")==0)
{
result=3.7854*x;
printf("%d %.4f l\n", i+1, result);
}
}
}
return 0;
}```
