in a book i saw that (complete reference to gcc)

(just typing in the terminal)

gives the executable result of hello.out

but it says to me command not found

could any one help me,and please tell me how to get the result of a executable

First off, that is only true if a) hello.out exists and b) the executable is in your $PATH. Assuming that hello.out exists, then you can simply type

in the directory of hello.out. The ./ tells your terminal to look in the current directory.

Just as a little advice: gcc has the -o option where you can give the executable after (successful) compilation whatever name you want, e.g.:

where Input_File.cpp is your source code.

[HTML]dheera@dheera-desktop ~ $ ls
Desktop hanumaan.c #*mail*#6153uil# NetBeansProjects untitled folder
dwhelper hanumaan.o #*mail*#6312Dtl# p Videos
Examples hello.c movies phanindra notes video songs
hanumaan hello.c~ myc Photos wall papers
#hanumaan.c# hellow naruto episodes Pictures
[/HTML]

after i got this as out put

[HTML]dheera@dheera-desktop ~ $ ls
a.out #hanumaan.c# hellow naruto episodes Pictures
Desktop hanumaan.c #*mail*#6153uil# NetBeansProjects untitled folder
dwhelper hanumaan.o #*mail*#6312Dtl# p Videos
Examples hello.c movies phanindra notes video songs
hanumaan hello.c~ myc Photos wall papers
[/HTML]

after i got this as

[HTML]dheera@dheera-desktop ~ $ a.out
bash: a.out: command not found
[/HTML]

The command 'echo $PATH' will output where you can place
an executable and expect it to work.

For all other locations, you will have to do the full path,
e.g. '/home/dheera/Desktop/a.out' or 'cd' to e.g. Desktop
and start the command with a dot : './a.out'
( The dot means the current directory )

And who says that all text in that book is correct ??

the ./ command is needed to be appended to the file you wish to execute.

if your executable abc.out is under the /home/myhome/testing folder

you would need to do this:
cd /home/myhome/testing folder
./abc.out


I hope this helps!
