scanf("%lf", &radius);

第二个是根据给定的余额和利息，计算一年以后的余额
void main()
{
double initBalance = 6000;
double interestRate = 0.0425;
printf("Interestcalculation program.\nStarting balance:%.lf Annual\ninterest rate percentage:%.4lf\n", initBalance,interestRate);

}
翻译为
编写程序，读取一个圆的半径和打印该圆的直径，周长和面积。使用值3.14159为“P”。写一个程序：承担起平衡6000年利率为4.25%。你的程序应该显示一年后的新的平衡。没有存款或退出–只是利息支付。你的程序应该能够重现以下samplerun：interestcalculation程序。startingbalance？6000annualinterest率？4.25balanceafter一年：6255
#include<iostream>
using namespace std;
const float pi=3.14;
void circle(float);
int main()
{
float R;
cout<<"please input the radius of a circle: ";
cin>>R;
circle(R);
return 0;
}
void circle(float r)
{

area=pi*r*r;

}
一楼的回答是固定的利率啊？应该由程序运行时输入的利率来计算才对的啊？
program First:
main()
{
float p=3.14159;
float r,d,l,s;
printf("r=");
scanf("%f",&r);
d=2*r;
l=2*p*r;
s=p*r*r;
printf("d=%4.2f l=%4.2f s=%4.2f\n",d,l,s);
getch();
}
program second:
main()
{
float a,p;
printf("Starting balance?");
scanf("%f",&a);
printf("Interest rate percentage?");
scanf("%f",&p);
a*=(1+p/100);
printf("Balance after one year: %4.0f\n",a);
getch();
}
呵呵，你在国外读书啊？题目竟然是用英文出的，不过看起来挺简单的啊

if(r <= 0)
cout<<"The radius should be over than 0 !"<<endl;
}
