Problem 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 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.
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

单位的转化吧,样例包含所有情况了。
上代码
#include <stdio.h> #include <string.h> void solve() { int t; int Case=0; scanf("%d",&t); while(t--) { double m; char a[155]; scanf("%lf",&m); scanf("%s",a); if(strcmp(a,"kg")==0) printf("%d %.4lf lb\n",++Case,m*2.2046); if(strcmp(a,"l")==0) printf("%d %.4lf g\n",++Case,m*0.2642); if(strcmp(a,"lb")==0) printf("%d %.4lf kg\n",++Case,m*0.4536); if(strcmp(a,"g")==0) printf("%d %.4lf l\n",++Case,m*3.7854); } } int main() { solve(); return 0; }
