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。就是这道题————Conversions
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:
Input
The first line of input contains a single integerN, (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
51 kg2 l7 lb3.5 g0 l
Sample Output
1 2.2046 lb2 0.5284 g3 3.1752 kg4 13.2489 l5 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;}希望大家可以帮帮忙，先谢谢了。
