suppose a class is as follows.. class cool { public: int a; int b; }; cool A[100];

now each element of array A[] has two sub elements 'a' and 'b'. Suppose we want to sort the array A[] in increasing order of 'a' and if two elements have equal 'a' then element with greater 'b' should be before. Can anyone give me the c++ code for the above purpose....
