Question

IN C LANGUAGE

You decide you want to build a skate park in your backyard, so you need to buy a lot of concrete. The good news is, you can get a discount when you buy in bulk. The price of concrete for different grades of concrete per cubic yard is as follows:

• when grade is either "low" or "cheap"
  • $100 (per cubic yard) for less than 200 cubic yards
  • $95 for between 200 and 400 (including 200 and 400) cubic yards
  • $90 for more than 400 cubic yards
• when grade is either "high" or "expensive"
  • $150 for less than 250 cubic yards
  • $135 for 250 or more cubic yards

Write a program that calculates the price of an order of concrete when given the grade and quantity.

Notes

• You can assume valid input.
• The grader is checking if your output ends with the integer dollar amount (no cents or punctuation).

Examples

What grade of concrete (low/cheap, high/expensive)?
low
How many cubic yards of concrete?
75
The cost is $7500

The answer to the example above is calculated from 75 * $100 (low grade, less than 200 cubic yards) = $7500

What grade of concrete (low/cheap, high/expensive)?
cheap
How many cubic yards of concrete?
75
The cost is $7500

What grade of concrete (low/cheap, high/expensive)?
high
How many cubic yards of concrete?
75
The cost is $11250

What grade of concrete (low/cheap, high/expensive)?
expensive
How many cubic yards of concrete?
75
The cost is $11250

Code:

#include<stdio.h>
#include<string.h>
int main()
{
   int yard;
   char concrete[15];/*Declaring variables*/
   printf("What grade of concrete(low/cheap,high/expensive)?\n");
   scanf("%s",concrete);
   printf("How many cubic yards of concrete?\n");
   scanf("%d",&yard);/*Reading input from the user*/
   if(strcmp("low",concrete)==0||strcmp("cheap",concrete)==0)
   { /*If low or chep*/
       if(yard<200)
       {/*If yard less than 200 we multiply yard*100*/
           printf("The cost is $%d",yard*100);  
       }
       else if(yard<=400)
       {/*If yard less than or equals 400 we multiply yard*95*/
           printf("The cost is $%d",yard*95);  
       }  
       else if(yard>400)
       {/*If yard greater than 400 we multiply yard*95*/
           printf("The cost is $%d",yard*90);
       }
   }
   else if(strcmp("high",concrete)==0||strcmp("expensive",concrete)==0)
   {/*IF high or expensive*/
       if(yard<250)
       {/*If yard less than 250 we multiply yard*150*/
           printf("The cost is $%d",yard*150);      
       }
       else
       {/*If yard grater or equals to 250 we multiply yard*135*/
           printf("The cost is $%d",yard*135);  
       }
   }
}
