error

[nidhan4u]

I am getting error in this code
main must return int==

#include<iostream.h>
#include<conio.h>
void main()
{
int a,b,c;
cout<<"enter the number";
cin>>a>>b;
c=a+b;
cout<<"required sum is"<<c;
getch();
}

[Denis]

void main should be int main

So you example should be

#include<iostream.h>
#include<conio.h>
int main()
{
int a,b,c;
cout<<"enter the number";
cin>>a>>b;
c=a+b;
cout<<"required sum is"<<c;
getch();
return 0;//should be return int
}

I am using Devc++ but i am not familiar with this. Please give me any link so that i can download Any other c++ compiler such that white screen turbo.

I think you just have to edit your source file.

[nidhan4u]

adding to my above post...
I am again getting two errors this time after using codes provided by you.

[nidhan4u]

These are the errors which i am getting now.

Try it again

#include<iostream>

int main()
{
    std::cout << "enter the number\n";
    int a(0);
    int b(0);
    std::cin>>a>>b;

    std::cout << "required sum is " << a+b << '\n';

    return 0;
}

Actually i am starting c++ again.
This time I am getting problem By using codes provided by you.
[Linker error] undefined reference to `__cpu_features_init'
ld returned 1 exit status

[Denis]

It seems that your compiler doesn't support C++ standard.

Please try g++4.x under Linux or VS 2008 express edition under Windows(also you can try MinGW)

[nidhan4u]

VS 2008 express edition under Windows

I will try this one.

[nidhan4u]

U mean that visual studio 2008.
I had that, as I am doing .NET. Can i use this for c++. coding.

[Denis]

shure

[nidhan4u]

can you plaese tell me how can i make use of that for c++..........I means in which option i have to go for writng source code.

[Denis]

try find in google by "how to create new console project in VS"

[nidhan4u]

file>new>project>visualc++>win32console applicatio

I had followed this path. Sir is it correct. and there i found this page.

// 3.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
