Question

How does the Child process generate using Fork() function.

For example: A process execute the code
fork()
fork()
fork()

Total Number of “child” process created is/are ?

Answer 1

Assuming that in Main you did total number fork as shown below then total 2power(3) = 8 processes will be created so, 8-1 =7 child process

To view the Processes use ps on linux

Eg:

#include <unistd.h>    
#include <sys/types.h>  
#include <errno.h>      
#include <stdio.h>      
#include <sys/wait.h>   
#include <stdlib.h>     

int main()
{
/*-------------your code part------------*/
    fork();
    fork();
    fork();
/*-------------your code part------------*/
}
