Question

Use only scanner class for input) 1. Write a program to calculate the simple interest by accepting the Principal amount ,rate per annum and time.(SI = pnr/100) 2. Write a program to accept the profit and cost price of a product and find the profit percentage.

Answer 1

Answer:

nope can't understand

Explanation:

please say properly

Answer 2

Answer:

Explanation:

1 #include <stdio.h>

int main()

{

float principle, time, rate, SI;

/* Input principle, rate and time */

printf("Enter principle (amount): ");

scanf("%f", &principle);

printf("Enter time: ");

scanf("%f", &time);

printf("Enter rate: ");

scanf("%f", &rate);

/* Calculate simple interest */

SI = (principle * time * rate) / 100;

/* Print the resultant value of SI */

printf("Simple Interest = %f", SI);

return 0;

}

// C++ implementation of above approach

#include <iostream>

using namespace std;

// Function to calculate the Selling Price

float SellingPrice(float CP, float PP)

{

// Decimal Equivalent of Profit Percentage

float P_decimal = 1 + (PP / 100);

// Find the Selling Price

float res = P_decimal * CP;

// return the calculated Selling Price

return res;

}

// Driver code

int main()

{

// Get the CP and Profit%

float C = 720, P = 13;

// Printing the returned value

cout << SellingPrice(C, P);

return 0;
