Visual Presentation:

Convert a decimal number to hexadecimal

Sample Solution:

C Code:

#include <stdio.h>  // Include the standard input/output header file. 
void main(){
  // Declare variables
long int decn,rmd,q,dn=0,m,l;
int i=1,j,tmp;
char s;
  // Print output header  
printf("\n\nConvert Decimal to Hexadecimal:\n ");
  // Get decimal input
printf("Input any Decimal number: ");
  // Store input
  q = decn;
  // Convert decimal to hex
  // Repeatedly divide decimal by 16
    // Get remainder
tmp = l % 16;
    // Convert to hex digit
if(tmp< 10){
tmp =tmp + 48; 
tmp = tmp + 55;
        // Accumulate hex number  
  // Print hex number
printf("\nThe equivalent Hexadecimal Number : ");
  // Print hex digits  
    s=m % 100;

Sample Output:

Convert Decimal to Hexadecimal:
