Write a C++ program to divide two integers (dividend and divisor) without using multiplication, division and mod operator

Sample Output:

```Dividend 7 Divisor 2
Result: 3
Dividend -17 Divisor 5
Result: -3
Dividend 35 Divisor 7
Result: 5
```

``````#include <iostream>
using namespace std;
int divide_result(int dividend_num, int divisor_num) {
if (dividend_num == INT_MIN && divisor_num == -1)
{
return INT_MAX;
}
bool minus = ((dividend_num > 0) ^ (divisor_num > 0));
long long num = labs(dividend_num);
long long div = labs(divisor_num);
int ans = 0;
while (num >= div)
{
long long temp = div;
long long mul = 1;
while(num >= (temp << 1))
{
mul <<= 1;
temp <<= 1;
}
ans += mul;
num -= temp;
}
return minus ? -ans: ans;
}
int main(void)
{
int dividend_num = 7;
int divisor_num = 2;
cout << "\nDividend " << dividend_num << " Divisor " << divisor_num << endl;
