Sample Solution:

C Code:

#include <stdio.h>

void main() 
        {
	long int decn,rmd,q,dn=0,m,l;
	int i=1,j,tmp;
        char s;

       printf("\n\nConvert Decimal to Hexadecimal:\n ");
       printf("-------------------------\n");

	printf("Input  any Decimal number: ");
	scanf("%ld",&decn);
	q = decn;
        for(l=q;l>0;l=l/16)
               {
		tmp = l % 16;
		if( tmp < 10)
		           tmp =tmp + 48; else
		         tmp = tmp + 55;
                         dn=dn*100+tmp;
	        }
          printf("\nThe equivalent Hexadecimal Number : ");
         for(m=dn;m>0;m=m/100)
            {
               s=m % 100;
               printf("%c",s);
            }
    printf("\n\n");
}

Sample Output:

Convert Decimal to Hexadecimal:                                                                               
 -------------------------                                                                                    
Input  any Decimal number: 79
