Perform division of two numbers in C language|using 6 ways

In this tutorial, we will discuss the Perform division of two numbers in C language

In this post, we are going to learn how to perform division of two numbers using different 6 ways

Division of two numbers

Division of two numbers – standard method

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num1,num2,division;//variable declaration
    num1=35,num2=5;//variable initialization
    division=num1/num2;//calculate division
    printf("Division of %d and %d is: %d",num1,num2,division);
    //display result on the screen
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Division of 35 and 7 is:5

Approach

Integer variable num1 and num2 both are declared and initialized
the num1 and num2 both are divided together and the value is assigned to the integer variable division
finally the program is displayed the output using printf() function

Division of two numbers – Using user input

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num1,num2,division;//variable declaration
    printf("Enter two numbers: ");//Ask the input from the user
    scanf("%d %d",&num1,&num2);//Store the given input
    division=num1/num2;//Calculate the division
    printf("division of %d and %d : %d",num1,num2,division);
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter two numbers: 1000
40
division of 1000 and 40: 25

Approach

Integer variable num1 and num2 both are declared,
The program takes input from the user
Then the user enters the value as input for num1 and num2
The program will read the input using scanf() function and store the variables in num1, num2.
The num1 and num2 both are divided together and the value assigned to the integer variable division
Finally the program is displayed the output using printf() function

Division of two numbers – Using function

Program 3

#include <stdio.h>
#include <stdlib.h>

int division(int,int);   //function prototype / declaration
int main()
{
    int num1,num2,result;
    printf("Enter two number\n");
    scanf("%d %d",&num1,&num2);  //numbers receive from the user
    result=division(num1,num2);//assign the output to variable result
    //function call
    printf("division of %d and %d is %d\n",num1,num2,result);
    getch();
    return 0;
}

int division(int a, int b)//function definition
{

        return a/b;
    }

When the above code is executed, it produces the following result

Enter two number
450
15
Division of 450 and 15 is: 30

Approach

Declare a function named as division() with two int parameters
Declare num1,num2 and result.
The program takes input from the user
Then the user enters the input value for num1, num2
the program will read the input using scanf() function and store the variables in num1, num2 respectively
define the function (division())to find division
Call the function to produce output
finally, the program displays the output using printf() function

Division of two numbers – Using recursion

Program 4

#include <stdio.h>
#include <stdlib.h>

int division(int,int);   //function prototype / declaration
int main()
{
    int num1,num2,result;
    printf("Enter two number to find division\n");
    scanf("%d %d",&num1,&num2);  //numbers receive from the user
    result=division(num1,num2);//assign the output to variable result
    //function call
    printf("Division of %d and %d is %d\n",num1,num2,result);
    getch();
    return 0;
}

int division(int x, int y)
{
    if (y==0)
{
  return 0;
}
else if (x-y==0){
  return 1;
}
else if (x<y){
  return 0;
}
else{
  return (1+division(x-y,y));
}
}

When the above code is executed, it produces the following result

Enter two number to find division

2400

Division of 2400 and 40 is: 60

Approach

Declare a function named as division() with two int parameters
Declare num1,num2 and result.
The program takes input from the user
Then the user enters the input value for num1 and num2
the program will read the input using scanf() function and store the variables in num1, num2 respectively
define the recursive function (division())to find division recursively
Call the function to produce output
finally, the program displays the output using printf() function

Division of two numbers – Using pointer

Program 5

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num1,num2,*ptr1,*ptr2,division;
    printf("Enter two number to find division\n");
    scanf("%d %d",&num1,&num2);  //numbers receive from the user
    //function call

    ptr1=&num1;
    ptr2=&num2;
    division=*ptr1 / *ptr2;
    printf("division of %d and %d is %d\n",num1,num2,division);
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter two number to find division
12345
15
Division of 12345 and 15 is: 823

Approach

Integer variable num1 and num2 both are declared,
Integer pointer variable *ptr1 and *ptr2 both are declared,
The program takes input from the user
Then the user enters the input value for num1 and num2
The program will read the input using scanf() function and store the variables in num1, num2.
Addresses of num1, num2 are assigned to variable ptr1 and ptr2 respectively
The pointer variables ptr1 and ptr2 both are used to divide given numbers together and the value is assigned to the integer variable of division
Finally the program is displayed the output using printf() function

Division of two numbers – without divisional operator

Program 6

#include <stdio.h>
#include <stdlib.h>

int division(int,int);   //function prototype / declaration
int main()
{
    int num1,num2,a,b,count=0;
    printf("Enter two number to find division\n");
    scanf("%d %d",&a,&b);  //numbers receive from the user

   num1=a;
   num2=b;
   while(num1>=num2)
   {
       num1=num1-num2;
       count++;
   }
    //function call
    printf("division of %d and %d is %d\n",a,b,count);
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter two number to find division

250

Division of 12345 and 15 is: 5
