C/C++ :: Comparing Two Arrays For Same Elements

int result = 1;
for (int j=0;j<N;j++) {
bool found = false;
for (int i=0;i<N && !found;i++) {
if (a[j] == b[i]) found = true;
}
if (!found) return 0;
}

I need to create a code that compares two in arrays without sorting them. They have to be the same length and contain the same elements in any order.

every integer in a[] is also in b[]
every integer in b[] is also in a[]
all such common values appear exactly the same number of times in both a[] and b[]

EX: a = {1, 2, 3}, b = {2, 3, 4} return 0 a = {1, 2, 3}; b = {2, 3, 1} return 1 a = {1, 2, 2}; b = {2, 2, 1} return 1 a = {1, 2, 2}; b = {2, 1, 1} return 0 a = {1, 1, 2, 2, 2}; b = {2, 1, 2, 1, 2} return 1

This is all i have...
