Try escaping double quotes, not doubling them ( \" ).

Use \" instead of double quote, but the error is still there

Add a semicolon before 'fi'. Also make sure you have spaces around your [[ ]]. In other words, make sure it works directly in shell first before trying to make it callable from C.

I did as suggested

Add a semicolon before 'fi'. Also make sure you have spaces around your [[ ]]. It worked !!

=========================================
#include <stdio.h>

int main()
{
system("if [[ \"$quotastat\" == \"\" ]]; "
"then "
"echo \"off\" > /var/apache/quota.status; "
"fi");
}
=======================================

jvannucci got it right !!!

and THANK YOU EVERYONE FOR PARTICIPATING.
