Can you put the output of a system function to a string

I am trying to find a way to put the output of a system command into a string but this is proving to be very difficult. I know it is possible to use a string inside of a system function but is it possible to use the output of the system function inside of a string.

I have no idea what you mean - please clarify. What language are you using? What system calls are you talking about? And what do you mean by "put the output into a string"? Do snprintf() and co. do what you want?

The easiest method is using popen + fgets + pclose.

I am using C++ language and I am wanting to put the output of the system() function into the string, in other words whatever the command i put into the system() function i want to be stored inside of a string.

The easiest method is using popen + fgets + pclose. Instead of function system. Please consult the manual for details.
