Question

write an algorithm,draw a flowchart and write its corresponding C program to convert a decimal number to its equivalent hexadecimal number.

Answer 1

Algorithm:

Step 1: Divide the original decimal number given in the question by 16

Step 2: Divide the quotient you get  by 16

Step 3: Repeat step 2 until we get quotient equal to zero.

Code:

#include<stdio.h>

int main() {

       long int decimalNumber,remainder,quotient;

       int i=1,j,temp;

       char hexadecimalNumber[100];

       printf("Enter any decimal number: ");

       scanf("%ld",&decimalNumber);

       quotient = decimalNumber;

       while(quotient!=0) {

               temp = quotient % 16;

               //To convert integer into character

               if( temp < 10)

                          temp =temp + 48; else

                        temp = temp + 55;

               hexadecimalNumber[i++]= temp;

               quotient = quotient / 16;

       }

       printf("Equivalent hexadecimal value of decimal number %d: ",decimalNumber);

       for (j = i -1 ;j> 0;j--)

             printf("%c",hexadecimalNumber[j]);

       return 0;

}

Answer 2

Thank you for asking this question.

/*

* C program to Convert Decimal to Hexadecimal

*/

#include <stdio.h>

#include<conio.h>

int main()

{

   long decim, quotient, remainder;

   int i, j = 0;

   char hexd[100];

    printf("Enter decimal number: ");

   scanf("%ld", &decim);

    quotient = decim;
