Question
make the following code work on LINUX:
include <windows.h>
#include <string>
#include <stdio.h>
#include <conio.h>
#include <process.h>
#include <dir.h>
#include <unistd.h>
using namespace std;
std::string current_working_directory()
{
char working_directory[MAX_PATH+1] ;
GetCurrentDirectoryA( sizeof(working_directory), working_directory ) ;
return working_directory ;
}
int main(void)
{
int i,j;
for(i=1;i<=2;i++)
{
if (mkdir("working_directorydiri",0777)==-1);
{
cerr<<"Error : "<<strerror(errno)<<endl;
exit(1);
}
else
{
cout << "Please enter j value: ";
cin >> j;
ofstream write ("working_directorydiri ilej.txt");
if (write.is_open())
{
write << "This is a new file."<<endl;
write.close();
}
else
cout << "Unable to open file";
}
if (j==20)
int symlink(const char *filej, const char *link1)
}
ofstream write ("working_directory ile1.txt");
if (write.is_open())
{
write << "This is the first file."<<endl;
write.close();
}
else
cout << "Unable to open file";
return 0;
}
Explanation / Answer
The problem is you don't define the symlink function you just called it in if(j==20) condition
For executing program in linux
Follow steps
Step 1. Use a text editor to create the C source code.
Type the command
gedit hello.c
and enter the C source code below:
#include <stdio.h>
main() {
printf("Hello World ");
}
Close the editor window.
Step 2. Compile the program.
Type the command
gcc -o hello hello.c
This command will invoke the GNU C compiler to compile the file hello.c and output (-o)
the result to an executable called hello.
Step 3. Execute the program.
Type the command
./hello
This should result in the output
Hello World
