i have created customized shell in c++. currently, shell designed infinite while loop started running corresponding executable terminal (i using ubuntu os). shell implements few new commands each stored separate executables in file system. rest of commands user enters directly executed using execve() wrapper function. so, essentially, executing user commands using execve() function: customised commands stored separate exectuables , " exec ed" providing path executable whereas other "standard" unix command directly exec ed. instead of running separate executable bash , want make user use shell executes on terminal . how can that? i referred following links: processes , sessions , controlling terminals creating unix shell however, unable figure out links association between controlling terminal , shell etc. appreciated in regards. update: this may sound bit illogical but: is there way implement user command user can execute current shell?i know

what connection between system.out.println() , tostring() in java? e.g: public class { string x = "abc"; public string tostring() { return x; } } public class ademo { public static void main(string[] args) { obj = new a(); system.out.println(obj); } } if main class runs, gives output "abc" . when remove code overrides tostring() , gives output "a@659e0bfd" . so, can explain working principle of system.out.println() when use parameter object? connected tostring() method? system.out printstream . printstream defines several versions of println() function handle numbers, strings, , on. when call printstream.println() arbitrary object parameter, the version of function acts on object . version of function ...calls @ first string.valueof(x) printed object's string value... looking @ string.valueof(object) , see returns if argument null, string equal "null"; otherwis
