I'm new to programming and I'm experimenting with very basic programs. I just wrote a program to convert USD to GBP. When I run the program I don't get the exact GBP value. For example if I enter 5 USD the program returns 3.25 GBP. However, the correct value should be 3.23. Here is the code. Can/will someone tell me what I'm doing wrong? Please.
#include <iostream>
#include <cmath>
using namespace std;
float dtp(float);
int main()
{
float dollar;
cout <<"Enter the dollar amount you want converted to Great Britain
Pounds: ";
cin >> dollar;
float pound = dtp(dollar);
if (pound <= 1)
{
cout <<"The dollar amount you entered of " << dollar <<" dollar is
equal to " << pound <<" pound.";
}
else
{
cout <<"The dollar amount you entered of " << dollar <<" dollars is
equal to " << pound <<" pounds.";
}
return 0;
}
float dtp(float p)
{
return p * .65;
}
根据我的计算器,5 * .65 = 3.25,这就是您得到的答案。
