私は少し初心者ですが、物事のハングアップを開始していますが、この男のためにこの電卓に別の部分を追加しています。エラー：C関数の宣言が前の宣言と矛盾しています
私はmain.cppとしてこれを持って、私はselection == 5ためのビットを追加しました：
#include <iostream>
#include <string.h>
using namespace std;
// Function includes
// I try to keep them in the order they appear in the
// output below for organization purposes
#include "calc.m.xy12plugin.cpp"
#include "calc.b.xymplugin.cpp"
#include "calc.m.xybplugin.cpp"
#include "calc.point.xymplugin.cpp"
#include "calc.parallelplugin.cpp"
// The above one would be here, too
int main(int argc, const char* argv[]) {
int i;
i = 0;
cout << "Linear Equation Calculator" << endl << "Copyright (c) 2011 Patrick Devaney" << endl
<< "Licensed under the Apache License Version 2" << endl;
// This loop makes the code a bit messy,
// but it's worth it so the program doesn't
// crash if one enters random crap such as
// "zrgxvd" or "54336564358"
while(i < 1) {
cout << "Type:" << endl
<< "0 to calculate a slope (the M value) based on two points on a line" << endl
<< "1 to calculate the Y-intercept (the B value) based on two points and a slope" << endl
<< "2 to calculate the slope (the M value) based on the Y-intercept and X and Y" << endl <<
"plug-ins" << endl
<< "3 to find the next point up or down a line based on the slope (M) and X and Y"
<< endl << "plug-ins" << endl
<< "4 to find a point x positions down the line based on the slope (M) and X and Y"
<< endl << "plug-ins" << endl
<< "5 to find the equation of a parallel line in form y=mx+c"
<< endl << "plug-ins" << endl;
string selection;
cin >> selection;
if(selection == "0") {
mcalcxyplugin();
i++;
}
else if(selection == "1") {
calcbxymplugin();
i++;
}
else if(selection == "2") {
calcmxybplugin();
i++;
}
else if(selection == "3") {
calcpointxymplugin(1);
i++;
}
else if(selection == "4") {
int a;
cout << "How many points up/down the line do you want? (Positive number for points" << endl
<< "further up, negative for previous points" << endl;
cin >> a;
calcpointxymplugin(a);
i++;
}
else if(selection == "5"){
calcparallelplugin();
i++;
}
else {
i = 0;
}
// End of that loop below
}
return 0;
}
私はその後、私は、これは
cal.parallelplugin.cppファイルです
else if(selection == "5"...
にリンクされ、このファイルを作成
#include <iostream>
using namespace std;
int main(){
cout <<"Welcome to the Parallel Line Calculator \n" << endl;
cout << "Here you will find the equation of the line parallel to a line passing through \na point (x,y) in the form y=mx+c \n\n" << endl;
float x,y, c, x1, y1, gradient, c1;
cout << "NOTE: Equation must be in form y=mx+c \n" << endl;
cout <<"Please enter the number of Xs:" <<endl;
cin >> x;
cout <<"Please enter the number of Ys:" <<endl;
cin >> y;
cout <<"Please enter the number of Cs:" <<endl;
cin >> c;
cout <<"Please enter the x co-ordinate:" <<endl;
cin >> x1;
cout <<"Please enter the y co-ordinate:" <<endl;
cin >> y1;
gradient= x/y;
c1 = y1 + (gradient*x1);
cout << "Equation of parallel line through (" << x1 << ", " << y1 << ") is " << "y=" << gradient << "x+" << c1 << endl;
}
私はこれをコンパイルエラーを得ることはありませんが、私は私が手main.cppにコンパイルする場合は、次の私が間違っているのかを作業私のすべての人生を過ごすことができないエラーと:(

HELP！
見た目では、**ファイル**ではなく、**機能**を使用する必要があります！ – chris
