Convert Decimal to Hexadecimal Number

The decimal (base ten) numeral system has ten possible values (0,1,2,3,4,5,6,7,8, or 9) for each place-value. In contrast, the hexadecimal (base sixteen) numeral system has sixteen possible values, using the letters A, B, C, D, E, and F for the six place-values after 9.
To avoid confusion while using different numeral systems, the base of each individual number may be specified by writing it as a subscript of the number. For example, the decimal number 512 may be written as 512₁₀ and read as "five hundred and twelve, base ten". The hexadecimal number 512 may be specified as "base sixteen" by writing it as 512₁₆ (which is 1298 when converted to decimal).

program:

#include<stdio.h>

#include<conio.h>

#include<process.h>

void main()

{

Int x, y=30, z;

clrscr();

printf(“Enter the number:”);

scanf(“%d”, &x);

printf(“\n conversion of decimal to hexadecimal number\n”);

for(;;)

{

if(x= =0)

exit(1);

z=x%16;

x=x/16;

gotoxy(y--,5);

switch(z)

{

Case 10:

Printf(“A”);

Break;

Case 11:

Printf(“%c”, „B?);

Break;

Case 12:

Printf(%c”, „C”);

Break;

Case 13:

Printf(“D”);

Break;

Case 14:

Printf(“E”);

Break;

Case 15:

Printf(“F”);

Default:

Printf(“%d”, z);

}

}

getch();

}

Output:

Enter the number: 31
