there's somthing....
 

I have installed RedHat 8.0 ....
I created a file called test.c
#include <stdio.h>
void main()
{
printf("test");
}

This is what I get in my terminal

[root@localhost]#gcc -o test test.c
[root@localhost]#./test
[root@localhost]#

so I can't open the file ....
than I downloaded some other *.c files
but I have the same problem

gcc filename.c -o filename
g++ filename.cpp -o filename

./filename

Does it compile at all? What do you see?

Did you setup execute permissions on it?
chmod a+x test
./test
HTH
-NSKL

this is on my screen...

[root@localhost]#gcc -o test test.c
[root@localhost]#./test
[root@localhost]#

theres no erorr messages thers nothing it compiles the program but i don't know why i can't open it ...
I send the exectuble file that i creating from compiling to my freind and he can open it but i can't open it....

yes i did it NSKL
