{ }

void main() { }

第三章 1：#include using namespace std; const float danwei=; void iswap(int cun) { }

void main() {

cout<<\您的身高为: \英尺!\int hour,minute;

cout<<\cin>>hour;

cout<<\cin>>minute; display(hour,minute);

cout<<\

}

int cun;

cout<<\请输入英寸单位的身高(整数):_______\\b\\b\\b\\b\\b\\b\cin>>cun; iswap(cun);

2：#include using namespace std; const double yingchi=12; const double bang=; const double memter=;

void caculate(double chi,double cun,double weight) { }

void main() {

double BMI;

double yingcun,mi,qianke; yingcun=cun+chi*yingchi; mi=yingcun*memter; qianke=weight/bang; BMI=qianke/(mi*mi);

cout<<\您的BMI值为: \

}

double chi,cun,weight;

cout<<\请输入身高(以几英尺几英寸方式输入): \cin>>chi>>cun;

cout<<\请输入体重(以磅为单位): \cin>>weight;

caculate(chi,cun,weight);

3：#include using namespace std; void main() {

double degrees,minutes,seconds,sum;

cout<<\cout<<\cin>>degrees;

cout<<\cin>>minutes;

cout<<\cin>>seconds;

sum=degrees+minutes/60+seconds/3600;

cout<

seconds= \

}

4：#include using namespace std; const long m=60; const long h=60; const long d=24; int sumday(long seconds) { }

int sumhour(long seconds,int day) {

long minute;

seconds=seconds-day*d*h*m; }

int summinute(long seconds,int day,int hour) {

minute=seconds/m; return minute/h; long hour,minute; minute=seconds/m; hour=minute/h; return hour/d;
