c++编程求助--已知某班成绩,设计程序计算并输出该班总人数,最高分,最低分和平均分？

Question

如题所述

Answer 1

int totalCount=0;//总人数
double totalScore = 0;
double maxScore = 0;//最高分
double minScore = 9999999;//最低分
double avgScore = 0;//平均分
vector<double> classScores;//这里存所有成绩，你得把这个赋值
for(int i = 0; i <classScores.size();i++)
{
totalCount++;
totalScore +=classScores[i];
if(maxScore < classScores[i]) maxScore = classScores[i];
if(minScore > classScores[i]) minScore = classScores[i];
}
avgScore =totalScore / totalCount;
