Question

Please have a look at the following code

#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
#include <sstream>


using namespace std;
bool isEven(int);


 int number;
 vector<int> inputNumbers;
 string line;

int main()
{    
    cout << "Please enter numbers: ";

    getline(std::cin,line);
    istringstream iss(line);

    while(iss>>number)
    {
        inputNumbers.push_back(number);
    }

    size_t vectorSize = inputNumbers.size();

    for(int i=0;i<vectorSize;i++)
    {
        cout << "Result for number " << i << "is: " << isEven(inputNumbers(i));
    }


}

bool isEven(int number)
{
    if(number%2 == 0)
    {
        return true;
    }
    else
    {
        return false;
    }
}

When I run this program, it gives the following error

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

BUILD FAILED (exit value 2, total time: 1s)

This won’t happen if I remove the function call to isEven(). Why is this happening? Please help!

Answer 1

Problem solved. I have replaced

inputNumber[i]

with

inputNumber(i)
