Determine a seller’s profit or loss and how much

Statement:

If cost price and selling price of an item is input through the keyboard, write a program to determine whether the seller has made profit or incurred loss. Also determine how much profit he made or loss he incurred.

ü           Algorithm:

                                    Step-1: Read a (cost price)

                                    Step-2: Read b (selling price)

                                    Step-3: if(a>b)

1)      Print “LOSS”

2)      c=a-b

3)      The amount loss is  c

                                    Step-4: else

1)      print “PROFIT”

2)      c=b-b

3)      The amount of profit c

                                    Step-5: End

                       

v                        Program Listing:

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

float a,b,c;

printf("Enter the cost price=");

scanf("%f",&a);

printf("\nEnter the selling price=");

scanf("%f",&b);

if (a>b)

{

printf("\nSeller incurred LOSS");

c=a-b;

printf("\nThe LOSS is=%f",c);

}

else

{

printf("\nSeller makes PROFIT");

c=b-a;

printf("\nThe PROFIT is=%f",c);

}

getch();

}

·        Output:

Enter the cost price= 102

Enter the selling price= 112

Seller makes PROFIT

The PROFIT is=10

Enter the cost price= 156

Enter the selling price= 114

Seller incurred LOSS

The LOSS is=42

                                   

           

           

§  Discussion:

                                                                                I.            It works within the number range -32767 to 32767

                                                                              II.            If we use long integer then it works in more than range.

                                                                            III.            It works in negative number.
