What do you see when you execute "pipe$1"?$ Why?

$$ Modify the program pipe$1.$cpp to pipe$1$a$.$cpp so that it accepts a command $($e$.$g$.,$ "cat pipe$1.$cpp$")$

from the keyboard. For example, when you execute $"./$pipe$1$a cat pipe$1.$cpp$",$ it should give you

the same output as pipe$1.$cpp$.$

$($Hint: Use string functions strcpy$()$ and strcat$()$ to store the commands in a buffer.

Your main function should be like: int main$($int argc, char $*$argv$[]))$

$3.$ The pipe Call $1\%$

The lower$-$level pipe$()$ function provides a means of passing data between two processes, without the

overhead of invoking a shell to interpret the requested command.
