Question

我的程序中有一个错误 'count'不能用作函数。

它指向以下行

mycount = (int) count (t1q1.begin(), t1q1.end(), 1);

我已经使用命名空间std包含了算法，但仍显示错误。

这就是我对矢量t1q1的处理方式下面的代码允许程序读入文件并提取某些信息并将其推回到向量

我的功能是阅读文件并将其存储在各种变量中

void checkForAnswers(char *ptr)
{
    char String[256];
    int count = 0;

    while ( *ptr != ':')
    {
        String[count] = *ptr;
        ptr++;
        count++;
    }

    String[count] = '\0';

     //if topic is 1.
     if (strcmp(String, "1") == 0)
    {
         currentPtr=Travels(':',startPtr);
         int answerone1 = (int)atoi(currentPtr);
         currentPtr=Travels(':',currentPtr);
         int answertwo2 = (int)atoi(currentPtr);
         currentPtr=Travels(':',currentPtr);
         int answerthree3 = (int)atoi(currentPtr);
         currentPtr=Travels(':',currentPtr);
         int answerfour4 = (int)atoi(currentPtr);
         currentPtr=Travels(':',currentPtr);
         int answerfive5 = (int)atoi(currentPtr);

         t1q1.push_back(answerone1);
         t1q2.push_back(answertwo2);
         t1q3.push_back(answerthree3);
         t1q4.push_back(answerfour4);
         t1q5.push_back(answerfive5);
    }

    if (strcmp(String, "2") == 0)
    {
        currentPtr=Travels(':',startPtr);
        int answerone1 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answertwo2 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answerthree3 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answerfour4 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answerfive5 = (int)atoi(currentPtr);

        t2q1.push_back(answerone1);
        t2q2.push_back(answertwo2);
        t2q3.push_back(answerthree3);
        t2q4.push_back(answerfour4);
        t2q5.push_back(answerfive5);
    }

     if (strcmp(String, "3") == 0)
     {
        currentPtr=Travels(':',startPtr);
        int answerone1 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answertwo2 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answerthree3 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answerfour4 = (int)atoi(currentPtr);
        currentPtr=Travels(':',currentPtr);
        int answerfive5 = (int)atoi(currentPtr);

        t3q1.push_back(answerone1);
        t3q2.push_back(answertwo2);
        t3q3.push_back(answerthree3);
        t3q4.push_back(answerfour4);
        t3q5.push_back(answerfive5);
    }

        currentPtr=0;
}

MY MAIN

  char Lines1[256];
        int count1 = 0;

        ifstream resultfile("results.txt");
        if (resultfile.is_open())
        {
            do
            {
            resultfile.getline(Lines1, 256);
            startPtr = Lines1;
            checkForAnswers(startPtr);
            count1++;
            }while(resultfile.eof() == false);
        resultfile.close();
        }


    int mycount;
    cout<< "\n";
    cout<< "TABULATION RESULTS\n";
    cout<< "------------------\n";
    cout<< "Topic 1, Question 1\n";
    mycount = (int) count (t1q1.begin(), t1q1.end(), 1);
    cout<< "Option 1: "<< mycount << " time(s)\n";

希望你们能够帮助我。在此先感谢帮助的人！：）

Answer 1

在您的代码count中引用局部变量count，其类型为int，因此不能用作函数。您应该将变量命名为其他名称，或者使用其限定名称std::count来引用该函数。

还要确保你#include <algorithm>（并且如果你去重命名变量并使用其非限定名称调用函数，则有一个适当的using声明。
