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;
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;
}```
