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.

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

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

 #include <stdio.h>

 #include <string.h>

 int main(){

     int T;

     double amount;

     char unit[];

     double total;

     int time;

     time=;

     scanf("%d",&T);

     while(T--){

         scanf("%lf%s",&amount,unit);

         printf("%d ",time);

         time++;

         if(strcmp(unit,"kg")==){

             total=amount*2.2046;

             printf("%.4lf lb\n",total);

         }

         else if(strcmp(unit,"lb")==){

             total=amount*0.4536;

             printf("%.4lf kg\n",total);

         }

         else if(strcmp(unit,"l")==){

             total=amount*0.2642;

             printf("%.4lf g\n",total);

         }

         else if(strcmp(unit,"g")==){

             total=amount*3.7854;

             printf("%.4lf l\n",total);

         }

     }

     return ;

 }
