Q24 Write a C program to convert from decimal to binary, octal, or hex number system.
#include<stdio.h>
void decimal_to_any_base(int number, int base)
{
int i, x, digits[1000], flag;
i = 0;
while(number)
{
x = number%base;
digits[i] = “0123456789abcdefghijklmnopqrstuvwxyz”[x];
number = number/base;
i++;
}
/* Removing leading zeros */
for(i–; i >= 0; i–)
{
if(!flag && digits[i] != ‘0’)
{
flag = 1;
}
if(flag)
{
printf(“%c”,digits[i]);
}
}
}
int main()
{
int number;
int base;
printf(“Give any number and base to covert in\n”);
scanf(“%d”,&number);
scanf(“%d”,&base);
printf(“Converting %d to the number base %d\n”,number, base);
decimal_to_any_base(number,base);
}
Output:
$ ./a.exe
Give any number and base to covert in
16
2
Converting 16 to the number base 2
10000
$ ./a.exe
Give any number and base to covert in
100
8
Converting 100 to the number base 8
144
$ ./a.exe
Give any number and base to covert in
100
16
Converting 100 to the number base 16
64
$ ./a.exe
Give any number and base to covert in
15
16
Converting 15 to the number base 16
