Thread: Total Beginner

Hello, this is my second ever attempt at writing a program. It is essentially a model of an economics paper I wrote. However, when I run it, after I enter the tax value it skips all the other inputs and then delivers an output.

What I am missing?

Code:

#include <cstdio>
#include <cstdlib>
#include <iostream>
using namespace std;

int main(int nNumberofArgs, char* pszArgs[])

{
    // Enter the tax
    int tax;
    cout << "Enter the tax rate [0,1]: "
    cin >> tax;

    // Enter the gdp (millions)
    int gdp;
    cout << "Enter the gdp level (millions): "
    cin >> gdp;

    // Enter the population (millions)
    int pop;
    cout << "Enter the population (millions: ";
    cin >> pop;

    // Enter the inflation rate
    int inflation;
    cout << "Enter the inflation rate: ";
    cin >> inflation;

    // Enter the openness
    int open;
    cout << "Enter the openness rate [0,1]: ";
    cin >> open;

    int intercept;
    intercept = 1.079;


    // Calculate FDI
    int fdi;
    fdi = intercept + tax * 2.24 + gdp * 1.786 + pop * 0.002 + inflation * -0.048 + open * 0.029;

    // Output the results (followed by NewLine)
    cout << "Fdi is: ";
    cout << fdi << endl;

    // wait until user is ready before terminating program
    // to allow the user to see the program results
    system("PAUSE");
    return 0;
}

This is a ctrl+a and copy & paste of the entire code. Unless there is another window I am missing?

Code:

//
//  FDI Calculator
//
//
//
#include <cstdio>
#include <cstdlib>
#include <iostream>
using namespace std;

int main(int nNumberofArgs, char* pszArgs[])

{
    // Enter the tax
    int tax;
    cout << "Enter the tax rate [0,1]: ";
    cin >> tax;

    // Enter the gdp (millions)
    int gdp;
    cout << "Enter the gdp level (millions): ";
    cin >> gdp;

    // Enter the population (millions)
    int pop;
    cout << "Enter the population (millions: ";
    cin >> pop;

    // Enter the inflation rate
    int inflation;
    cout << "Enter the inflation rate: ";
    cin >> inflation;

    // Enter the openness
    int open;
    cout << "Enter the openness rate [0,1]: ";
    cin >> open;

    int intercept;
    intercept = 1.079;


    // Calculate FDI
    int fdi;
    fdi = intercept + tax * 2.24 + gdp * 1.786 + pop * 0.002 + inflation * -0.048 + open * 0.029;

    // Output the results (followed by NewLine)
    cout << "Fdi is: ";
    cout << fdi << endl;

    // wait until user is ready before terminating program
    // to allow the user to see the program results
    system("PAUSE");
    return 0;
}

Weird. When I hit 'Run', I can only enter one value, it just skips past the rest...

Spot on. I should have seen that.

Hi, I have a new problem with the same program so I thought I would keep it in here. So far I have:

Code:

//
//  FDI Calculator
//
//
//
#include <cstdio>
#include <cstdlib>
#include <iostream>
#include <stdio.h>
#include <math.h>
using namespace std;

int main(int nNumberofArgs, char* pszArgs[])

{
    double     intercept;
    double     gdp;
    int        pop;
    double     inf;
    int        fdi;
    double     tax;
    double     open;
    int        country;

    cout << "Welcome to the FDI Calculator ";
    system("PAUSE");

    // Choice of country

    cout << "Enter your choice of country, ie. 8 = 'Ireland': ";
    cin  >> country;

    switch (country)
    {
        case 8:
            fdi =       11979;
            tax =       0.125;
            gdp =       201.93;
            pop =       4;
            inf =       118.38;
            open =      151.44;
            break;

        default:
            fdi =       0;
            tax =       0;
            gdp =       0;
            pop =       0;
            inf =       0;
            open =      0;
    }

    // Calculate current expected FDI

    cout << "Current expected FDI for this country is: ";
    fdi << endl;


    // Enter the tax
    double newtax;
    cout << "Enter your proposed tax rate [0,1]: ";
    cin >> newtax;


    intercept = 1.079;


    // Calculate FDI
    double logfdi;
    logfdi = intercept + log(newtax) * -2.24 + log(gdp) * 1.786 + log(pop) * 0.002 + log(inf) * -0.048 + log(open) * 0.029;

    // Output the results (followed by NewLine)
    cout << "% Change in Fdi is: ";
    cout << logfdi << endl;

    system("PAUSE");

    int oldfdi;
    cout << "Enter current FDI [bea]: ";
    cin >> oldfdi;

    double newfdi;
    newfdi = oldfdi*(1+(logfdi/100));

    cout << "FDI levels are now: ";
    cout << newfdi << endl;

    // wait until user is ready before terminating program
    // to allow the user to see the program results
    system("PAUSE");
    return 0;
}

When I attempt to build this I get:


C:\Beginning_Programming-CPP\FDI_Elasticity\main.cpp||In function 'int main(int, char**)':|
C:\Beginning_Programming-CPP\FDI_Elasticity\main.cpp|56|error: invalid operands of types 'int' and '<unresolved overloaded function type>' to binary 'operator<<'|
||=== Build finished: 1 errors, 0 warnings ===|


What am I doing wrong here?

Thanks

I assume this is it:

Code:

cout << "Current expected FDI for this country is: ";
fdi << endl;

You are attempting to use fdi as if it were a stream. You need to replace the ; on the line immediately above it with the extraction operator ( << )

That's it, thank you!
