Windows 10: Error in vs code while running graphics C++program

Hello, I'm facing error while tryin to run C++ program with graphics.h file included in Microsoft VS code.I'm using TDM-GCC-32 g++ compiler to compile the program and the program builds successfully.However when I go to new terminal and try to run the file by pressing "./filename" in the project folder, I get this error "the term "./filename is not recognized as the name of cmdlet, function, script file or openable program...."I have mingw32 also installed on the system in system variables.I just can't keep my finger on what the error is, I'm new to coding. The same program use to work in devc

Coding language for BIOS?

That is what I was figuring. C or Assembly. I really like coding in C, so far more then C++.

Reading over that UEFI Programming steps website. Really cool stuff.

 

when i rebuild bcd,run bcdedit /export c:\bcdbackup,An error occurred

an ERROR IS The storage export operation has failed and the system cannot find the specified FILE

because when laptop startup,screen display Not connected or unable to access the required device
Error code 0Xc000000e

but，i run bcdedit /export d:\bcdbackup,The screen shows that the operation was successful

I run these commands step by step

1.bootrec /fixmbr

2.bootrec /fixboot

3.bootsect /nt60 sys

4.bootrec /fixboot

5.bcdedit /export c:\bcdbackup

6.attrib c:\boot\bcd -h -r -s

7.ren c:\boot\bcd bcd.old

8.bootrec /rebuildbcd

An error occurred in the fifth step

i use diskpart and list volume

Disk C is only 260M, Disk H is the system disk, Disk D is a removable disk

so What command should I enter in the fifth step

 

Learning to Program C

my suggestion is to learn c first, then expand to c++ or java depending on your project requirements. if you decide to use visual studio (which i strongestly recommend) then you can just create c++ projects and write normal c code
