I received an error while trying to run the following code, why is this happening? Do the sort function have any additional requirements for the comparison function

run the code

#include<algorithm>
using namespace std;

bool cmp(int i,int j){
    return i<=j;
}
int main(){
    int n=42;
    int arr[]={36,0,21,52,13,24,47,88,83,19,36,50,85,37,6,85,43,18,11,100,78,43,0,43,18,99,38,62,56,82,16,81,22,75,33,80,34,57,30,5,58,91};
    sort(arr,arr+n,cmp);
    return 0;
}

Microsoft Visual C++ Runtime Library:
Expression: invalid comparator
