Create n-child process from same parent process using fork() in C

fork() is a system call function which can generate child process from parent main process. Using some conditions we can generate as many child process as needed. We have given n , we have to create n-child processes from same parent process (main process ). Examples:

Input :3
Output :[son] pid 25332 from [parent] pid 25329
 [son] pid 25331 from [parent] pid 25329
 [son] pid 25330 from [parent] pid 25329

here 25332,25331,25330 are child processes from same parent process
with process id 25329 

Input :5
Output :[son] pid 28519 from [parent] pid 28518
 [son] pid 28523 from [parent] pid 28518
 [son] pid 28520 from [parent] pid 28518
 [son] pid 28521 from [parent] pid 28518
 [son] pid 28522 from [parent] pid 28518

here 28519,28520,28521,28522,28523 are child processes from same parent process
with process id 28518.

Output:

[son] pid 28519 from [parent] pid 28518
[son] pid 28523 from [parent] pid 28518
[son] pid 28520 from [parent] pid 28518
[son] pid 28521 from [parent] pid 28518
[son] pid 28522 from [parent] pid 28518
