C program to convert decimal number to hexadecimal number.

source 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:", decimal Number);    for(j = i -1 ;j> 0;j--)

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

 getch();

 return 0;
