C Exercises: Divide two given integers without using multiplication, division and mod operator
C Programming Practice: Exercise-15 with Solution
Write a C programming to divide two given integers without using multiplication, division and mod operator. Return the quotient after dividing.
C Code:
#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
int divide_two(int dividend_num, int divisor_num)
{
int sign = (float) dividend_num / divisor_num > 0 ? 1 : -1;
unsigned int dvd = dividend_num > 0 ? dividend_num : -dividend_num;
unsigned int dvs = divisor_num > 0 ? divisor_num : -divisor_num;
unsigned int bit_num[33];
unsigned int i = 0;
long long d = dvs;
bit_num[i] = d;
while (d <= dvd) {
bit_num[++i] = d = d << 1;
}
i--;
unsigned int result = 0;
while (dvd >= dvs) {
if (dvd >= bit_num[i]) {
dvd -= bit_num[i];
result += (1<<i);
} else {
i--;
}
}
if (result > INT_MAX && sign > 0) {
return INT_MAX;
}
return (int) result * sign;
}
int main(void)
{
int dividend_num = 15;
int divisor_num = 3;
printf("Quotient after dividing %d and %d : %d", dividend_num, divisor_num, divide_two(dividend_num, divisor_num));
return 0;
}
Sample Output:
Quotient after dividing 15 and 3 : 5

Maximum value of int:
In C:
#include <limits.h> then use int imin = INT_MIN; // minimum value int imax = INT_MAX;
or
#include <float.h> float fmin = FLT_MIN; // minimum positive value double dmin = DBL_MIN; // minimum positive value float fmax = FLT_MAX; double dmax = DBL_MAX;
