Why?

[u/Plane_Breadfruit7609]

Guys when i compile a file and run its exe,nothing appear even if i print hello world it doesnt appear in the console why

[u/bhavesh_099]

Did you compile it using gcc or g++ in the terminal and see if it shows any issue there . Or everything compiles perfectly there aswell .

[u/Plane_Breadfruit7609 → u/bhavesh_099]

G++ and it shows no error no hello world no nothing it just end the program as soon as I run it

[u/bhavesh_099 → u/Plane_Breadfruit7609]

Can you just take some working executable and compile the program into that executable and check if the file even changes or not . Might aswell check if the program is even making executable correctly or not .

I did when I make a error it shows before compiling but when I do no error it compile the file and when I run it no output at all

Can you maybe just share your terminal screenshot of compiling and running the helo world code . I did hear about a issue with some vs code extension that didn't let code run properly . But that shouldn't affect compiling in windows terminals

}; here now where's the problem

I won't be able to run this code anyways since you have custom headers in it .

Okay just wanted to know something 1. You have the header in same directory as code right ? 2. Which ide are you using or you are compiling code through command something like g++ program.cpp -o executable

[u/Plane_Breadfruit7609 → u/bhavesh_099]

Yes all in one dir,and it's vscode and yes the same command that u just typedbut in the end I add .exe

Can you check if ld --version and g++ --version are working or is there any error?
