BASH arrays and variables of variables in C++

Sometimes it is handy to protect long scripts in C++.

The following syntax works fine for simple commands:

Code:
#define SHELLSCRIPT1 "\
#/bin/bash \n\
echo \"hello\" \n\
"
int main ()
{
cout <<system(SHELLSCRIPT1);
return 0;
}


Unfortunately for there are problems for:
1d arrays: array=(a1 a2 a3)

error message: sh: 12: Syntax error: "(" unexpected
and
variables of variables:
Code:
var=VAR
k=0
VAR0=good
echo $VAR0; echo blah
eval "echo "\$$var$k""



error message: warning: unknown escape sequence: '\$' [enabled by default]

Please excuse my ignorance ... Is there a solution? What are the limitations of the aforementioned C++. Calling a Bash script from C++ is not the optimum solution for my case. The script needs to be inside the .cpp

Thanks
