If the total selling price of 15 items and the total profit earned on them is inputed through the keyboard write a program on C plus plus to find the cost price of one item help would be great?

Answer 1

#include<conio.h>

#include<stdio.h>

void main(void)

{

int sell_pr, profit, cost_pr, cost_pr_one_item ;

clrscr();

printf("Please enter the selling price of 15 items:");

scanf("%d", &sell_pr);

printf("Please enter the profit earned on 15 items:");

scanf("%d", &profit);

cost_pr = sell_pr - profit;

cost_pr_one_item = cost_pr/15;

printf("Cost price of one item is %d", cost_pr_one_item);

getch();

}

Answer 2

#include<iostream>

#include <string>

#include <sstream>

using namespace std;

double enter_double( string prompt, unsigned int multiple = 15, double min = 0.0 )

{

string input;

double result;

while( 1 )

{

printf( "Enter the %s of %u items: ", prompt.c_str(), multiple );

getline( cin, input );

stringstream( input ) >> result;

if( result < min )

{

printf( "\nERROR: The %s cannot be less than %0.2f\n", prompt.c_str(), min );

continue;

}

result *= 100;

int i = (int) result;

if( i/multiple != result/multiple )

{

printf( "\nERROR: The %s must be an exact multiple of %u\n", prompt.c_str(), multiple );

continue;

}

result = (double)i / 100;

break;

}

printf( "You entered %.2f\n", result );

return( result );

}

int main()

{

double total_selling_price;

double total_profit;

double total_cost;

double item_cost;

total_selling_price = enter_double( "total selling price", 15, 0.15 );

total_profit = enter_double( "total profit", 15, total_selling_price * (-1) );

total_cost = total_selling_price - total_profit;

printf( "Total cost: %0.2f\n", total_cost );

item_cost = total_cost / 15;

printf( "Cost per item: %0.2f\n", item_cost );

return(0);

}

Output:

Enter the total selling price of 15 items: 150.15

You entered 150.15

Enter the total profit of 15 items: 30.45

You entered 30.45

Total cost: 119.70

Cost per item: 7.98
