我無(wú)法按照規(guī)范完成作業(yè) . 這是分配方案：

大學(xué)迫切需要一個(gè)自動(dòng)測(cè)試評(píng)分系統(tǒng) . 使用C，為大學(xué)寫(xiě)一個(gè)評(píng)分系統(tǒng)，并對(duì)至少五名學(xué)生的測(cè)試進(jìn)行評(píng)分 . 要?jiǎng)?chuàng)建評(píng)分系統(tǒng)，請(qǐng)按照以下步驟操作：首先詢問(wèn)測(cè)試中的問(wèn)題數(shù)量然后詢問(wèn)每個(gè)問(wèn)題的正確答案 . 請(qǐng)注意，多項(xiàng)選擇測(cè)試和問(wèn)題將從A到D得到答案 . 詢問(wèn)學(xué)生人數(shù)并通過(guò)詢問(wèn)他們的姓名來(lái)處理每個(gè)學(xué)生，然后循環(huán)詢問(wèn)學(xué)生的答案 . 為每個(gè)問(wèn)題打分 . 在最后一個(gè)問(wèn)題計(jì)算出學(xué)生得分后，顯示“學(xué)生'插入學(xué)生姓名'得分為20分中的10分或50％ . ”重復(fù)，直到所有學(xué)生都得分 . 在對(duì)所有學(xué)生進(jìn)行評(píng)分后，以與以前相同的方式插入打印所有學(xué)生成績(jī)的 class 列表 .

這是我到目前為止：

#include "stdafx.h"

#include

#include

#include

#include

using namespace std;

int _tmain(int argc, _TCHAR* argv[])

{

//declare variables

char choice;

string studentName;

vector answers;

vector names;

int getStudents();

int getQuestions();

//calls function to get number of questions

float questions = getQuestions();

//Get answers

for (int i = 0; i < questions; ++i) {

cout << "What is the answer for question " << i + 1 << endl;

cin >> choice;

answers.push_back(choice);

}

//Get number of students

int students = getStudents();

//Get student names

for (int i = 0; i < students; i++) {

cout << "Student " << i + 1 << ", what is your name?" << endl;

cin >> studentName;

names.push_back(studentName);

}

float score = 0;

char studentAnswer;

vector userAnswer;

vector finalScore;

//gets student answers

for (int i = 0; i < students; i++) {

for (int j = 0; j < questions; j++) {

cout << names[i] << ", what is your answer for question " << j + 1 << "?" << endl;

cin >> studentAnswer;

userAnswer.push_back(studentAnswer);

}

}

//calculates student scores

for (int i = 0; i < students; i++) {

for (int j = 0; j < questions; j++) {

if (userAnswer[j] == answers[j])

score = score + 1;

}

finalScore.push_back(score);

}

//outputs scores

for (int i = 0; i < students; i++) {

cout << names[i] << " scored " << finalScore[i] << " out of " << questions <<

" or " << (finalScore[i] / questions) * 100 << "%" << endl;

}

system("pause");

return 0;

}

//function to get number of questions

int getQuestions()

{

int questions;

cout << "How many questions are there?" << endl;

cin >> questions;

return questions;

}

//function to get number of students

int getStudents()

{

int students;

cout << "How many students are there?" << endl;

cin >> students;

return students;

}

最終得分返回的值不準(zhǔn)確，我找不到錯(cuò)誤發(fā)生的位置 .

同樣，為了在最后一步中進(jìn)行排序，我被要求按升序或字母順序按降序和名稱排序 . 我能夠相互獨(dú)立地排序這些，但不知道如何將它們組合起來(lái)并按照這種方式對(duì)它們進(jìn)行排序 .

創(chuàng)作挑戰(zhàn)賽新人創(chuàng)作獎(jiǎng)勵(lì)來(lái)咯，堅(jiān)持創(chuàng)作打卡瓜分現(xiàn)金大獎(jiǎng)

總結(jié)
