10. Write a program to calculate bill of a job work done as follows. Use if else statement. a) Rate of typing 3 Rs/page b) Printing of 1st copy 5Rs/pages & later every copy 3Rs/page. The user should enter the number of pages and print out copies he/she wants.

#include<stdio.h>

#include<conio.h>

void main()

{

     int page,type;

     clrscr();

     printf("\nA. rate of typing 3rs/page");

     printf("\nB. printing of 1st copy 5rs/page & later every copy 3rs/page");

     printf("\n\nenter the number of typing pages: ");

     scanf("%d",&type);

     printf("\nenter the number of copies: ");

     scanf("%d",&page);

     if(type>=1)

     {

         type = type * 3;

     }

     else

     {

         printf("\nenter valid number");

     }

     if(page>=1)

     {

         page = page - 1;

         page = (page*3)+5;

     }

     else

     {

         printf("enter valid number");

     }

     printf("\n\ntyping charges: %d",type);

     printf("\nprinting chargis: %d",page);

     printf("\n================================");

     printf("\ntotal charges: %d",type + page);

     printf("\n================================");

     getch();

}

/*  output:

A. rate of typing 3rs/page

B. printing of 1st copy 5rs/page & later every copy 3rs/page

enter the number of typing pages: 23

enter the number of copies: 34

typing charges: 69

printing chargis: 104

================================

total charges: 173

================================
