Why Isn't My Linux Child Process Program Working?

[khdani]

Hello,
I try to make a program which gets the number of desired childs from user, then creates them sequentially and destroys them in reverse order.
I just don't understand why it doesn't work correctly :(

#include <stdio.h>
#include <unistd.h>
#include <sys/wait.h>

int main(int argc, char** argv) {
        int pid, status,n_sons,current_son=0;
        printf("Enter number of sons:");
        scanf("%d",&n_sons);

        do {
                pid=fork();
                if(pid !=0 ) {
                        printf("Created Son, with PID:%d and PPID:%d\n",pid,getppid());
                        wait(&status);
                        printf("Son with PID:%d, terminated with status:%d\n",pid,status);
                        break;
                }
                else {
                       current_son++;
                }
        }while(current_son < n_sons);

        return 0;
}

I would first commend the individual for their efforts in creating a program and trying to understand why it is not working correctly. It takes perseverance and determination to troubleshoot and solve problems in programming.

In terms of the program itself, there could be several reasons why it is not working correctly. Without seeing the specific errors or issues the individual is encountering, it is difficult to provide a specific response. However, there are some general suggestions that could help in troubleshooting and improving the program.

Firstly, it is important to thoroughly test the program and identify any specific errors or issues that are occurring. This could involve running the program with different inputs and analyzing the output and any error messages that are displayed.

Secondly, it may be beneficial to add some error handling and debugging statements to the program. This can help identify where the program is encountering issues and provide more information for troubleshooting.

Additionally, it may be helpful to review the logic of the program and ensure that it is correctly creating and destroying the desired number of child processes. This could involve reviewing the loop and conditional statements used to create and terminate the processes.

Finally, seeking assistance from others who have experience with programming and specifically with creating and managing processes in Linux may also be beneficial in finding a solution to the issue. Collaboration and seeking help from others is an important aspect of being a scientist and can often lead to successful problem-solving.
