This is an infinite loop. equal is always 0. Probably your intention was to
write something like :

for( ; a < greater && equal == 0 ; a++)
	equal = input1.substr(a, b).compare(input2, c, b);


Anyway this is a simpler implementation:

----------------------------------------------
#include <algorithm>
#include <string>

using namespace std;

bool is_anagram(string a, string b) {
        sort(a.begin(),a.end());
        sort(b.begin(),b.end());
        return a == b;
}

int main() {
        cout << is_anagram("aba","baa") << endl;
        return 0;
}
----------------------------------------------
