Week 8 : Programming Assignment 1

Write a C Program to find HCF of 4 given numbers using recursive function

Select the Language for this assignment.

#include<stdio.h>
int HCF(int, int); //You have to write this function which calculates the HCF. 
     
int main()
{
   int a, b, c, d, result;
   scanf("%d %d %d %d", &a, &b, &c, &d); /* Takes 4 number as input from the test data */
   result = HCF(HCF(a, b), HCF(c,d));
   printf("The HCF is %d", result);
}
 
//Complete the rest of the program to calculate HCF

int HCF(int x, int y)
{
   while (x != y)
   {
      if (x > y)
       {
           return HCF(x - y, y);
       }
       else
       {
       return HCF(x, y - x);
       }
    }
    return x;
}

You may submit any number of times before the due date. The final submission will be considered for grading.

This assignment has Public Test cases. Please click on "Compile & Run" button to see the status of Public test cases. Assignment will be evaluated only after submitting using Submit button below. If you only save as or compile and run the Program , your assignment will not be graded and you will not see your score after the deadline.

Write a C Program to print Binary Equivalent of an Integer using Recursion

Select the Language for this assignment.

#include <stdio.h>
int binary_conversion(int); //function to convert binary to decimal number
int main()
  {
  int num, bin;  //num is the decimal number and bin is the binary equivalent for the number
 
  scanf("%d", &num); //The decimal number is taken from the test case data
  bin = binary_conversion(num); //binary number is stored in variable bin
  printf("The binary equivalent of %d is %d", num, bin);
  return 0;
  }

int binary_conversion(int num)
  { 
     if (num == 0)
        {
            return 0;
        }
        else
        {
            return (num % 2) + 10 * binary_conversion(num / 2);
        }
  }

Write a C Program to reverse a given word using function.
e.g. INDIA should be printed as AIDNI

Select the Language for this assignment.

#include<stdio.h>
#include<string.h>
 
void reverse(char[], int, int);
    int main()
    {
        char str1[20];
        scanf("%s", str1); //The string is taken as input form the test data. 
     
/* Complete the program to print the string in reverse order using the function
void reverse(char[], int, int);
Use the printf statement as
printf("The string after reversing is: %s\n", str1); 
You can use different variable also.
*/

reverse(str1, strlen(str1), 0);
        printf("The string after reversing is: %s", str1);
        return 0;
}
 
void reverse(char str1[], int len, int i)
{
  char temp;
  for(int i=0; i<len/2; i++)
  {
    temp = str1[i];
    str1[i] = str1[len-i-1];
    str1[len-i-1] = temp;
  }
  str1[len]='\0';
}
