c++ - Overflow pow function with long long?

Question

I have a problem defining a pow function for long long values, this is the code:

long long int pow( long long int base, long long int exp){
    long long int count = 1;
    for(int i=exp; i>=0; i--){
        if(i==0) {break;}
        if(exp==1) {count = count * base; break;}
        count = count * base;
    }
    return count;
}

it is necessary to use iteration and not to be recursive, if I print the function for 2^i for I up to 63 from a certain moment on it computes 0, it is an overflow error? how can I avoid it?
