C語(yǔ)言 學(xué)生成績(jī)求和

#include "iostream"

#include "iomanip"

using namespace std;

void main()

{

double a[4];

cout"請(qǐng)輸入4個(gè)學(xué)生的成績(jī)";

cina[0]a[1]a[2]a[3];

double d,min;

d=a[0]+a[1]+a[2]+a[3];

min=d/4;

cout"四個(gè)學(xué)生的總成績(jī)?yōu)椋?dendl;

cout"平均成績(jī)?yōu)椋?fixedsetprecision(2)minendl;

}

最后的cout里面設(shè)置了輸出個(gè)精度為小數(shù)點(diǎn)后面兩位。妄采用。
