show your code

#paste

#include<stdio.h> int main() { printf("Hello world"); return 0; }

then your toolchain is probably wrongly configured

how have you configured it?

no

you haven't set up your toolchain?

how to configured etc etc

i start learning from youtube.. and i download visual studio as IDE and compiler as MinGw

visual studio doesn't come with MSVC? so you cannot compile within visual studio and that's why you use terminal?

ok

i start learning from youtube.. and i download visual studio as IDE and compiler as MinGw

why not use msvc if you are using vs anyway?

ok

what do you mean by "ok"? ... that was a normal question

youtuber recommended to download Mingw as compiler

i just started learning c programming yesterday .. so i dont know so much

i will tell yu step by step .. plz help me

step 1-i download visual studio

step2-I download Mingw and add to path in MY PC

i started writing my 1st command .. its showed error

thats it

hm...

code -#include<stdio.h> int main() { printf("Hello world"); return 0; }

and you are 100% sure that the data has been written to the disk and is not just in visual studio right?

yes

1 sec

msvc is better than mingw

It is a linker error. The linker is looking for WinMain function instead of main. When you created a project, did you choose Windows Application instead of Console Application?

how to solved it?

Create a new project and choose console application as project type

afaik his file is just the main.c

if you do gcc instead of g++ is there any change?

afaik his file is just the main.c

Yes but the main.o is linked with the runtime library. If the project settings says it is a Windows application, then the start up code in the run time library will call WinMain function and not main. Since there is no WinMain in his code, the linker is complaining about it

what project settings? he is just running g++, that won't load some extra configuration will it?

PS C:\c tutorials> gcc main.c /mingw/lib/libmingw32.a(setargv.o):(.text+0x33): undefined reference to `__chkstk_ms' /mingw/lib/libmingw32.a(main.o):(.text.startup+0xa0): undefined reference to `WinMain@16' collect2: ld returned 1 exit status

same error

how does your path looks

yes

How does your path looks?

https://stackoverflow.com/questions/18649173/how-to-solve-undefined-reference-to-chkstk-ms-on-mingw

C:\MinGW\bin

Ok. I thought he was getting that error from Visual Studio. Didn't see the command line.

C:\MinGW\bin

that's your whole path right?

yeah its my whole path

damn i dont know windows but shouldn't there be more things just one directory? /o\

Light Look at the link in this message. It says how you should solve this error.

lets try

if its works then fine

and thanks for giving time for my problem

is this not working cause I am trying to assign an int type to an address?**int main(){ int a =0 ; int b =1; int *ptr=&a; std::cout<<"Initial Value: "<<*ptr <<"\n"; *ptr=&b; std::cout<<"Changed Value: "<<*ptr<<"\n"; }**

Ok got it , Thanks

how can i convert TCHAR to string?

I google it but I did not understand

how can i convert TCHAR to string?

https://stackoverflow.com/questions/6291458/how-to-convert-a-tchar-array-to-stdstring

https://stackoverflow.com/questions/6291458/how-to-convert-a-tchar-array-to-stdstring

std::string BinRes::getAppLocation() { TCHAR szPathName[128]; std::string strPath; GetModuleFileName(NULL, szPathName, 128); strPath = szPathName; int slashPos = strPath.rfind('\\'); if(slashPos == strPath.npos) throw "Unable to get exe location"; strPath = strPath.substr(0, slashPos); return strPath; } strPath = szPathName; in this line I have this error: Error (active) E0349 no operator "=" matches these operands what should I do ? I am not familiar with winbase syntax:(

my problem is this👆 and I thought maybe I can convert TCHAR to string

#include<iostream> using namespace std; int main(){ char b; string t= "hollder"; string a = "Amish"; int x = a.length(); for(int i = 0 ;i < x;i++){ if(t.find(a[i])){ cout << a[i]<< endl; } } return 0; }

I Want to print all nos in string a which are in string string t, that is "h" but its not working how I intended it to, its doing quite the opposite its prinnting A m i s in different lines without h

remove the endl from cout if you want it to print in the same line. e.g cout < < "hello"; for t.find(a[i]) refer to it's documentation to know what it accepts, returns and what it does.

In your case t.find(a[i]) you're just finding the position of each and every letters in string a. So when the i = 0 in loop, a[i] = a[0] = "h", but since "h" is at 0th position in string t, t.find(a[0]) returns 0 as expected, 0 means false, so the if condition won't happen for "h", but will happen for every other characters because anything other than 0 is true.

but because every S* system/environment/program is different
