Assignment: For this assignment you’ll be designing a program which can take the input of a decimal number and a numerical base, and convert the decimal number to that base. For example, if given the decimal number seven and the base two, your program should output it as 111, which is how seven is represented in binary.

You’ll need to perform these operations on the following combinations:

A: 15, base 2.

B: 38, base 16.

C: 54, base 6.

D: 19, base 8.

E: 27, base 3.

Explanation / Answer

#include <stdio.h>
#include <string.h>

char reVal(int num)
{
if (num >= 0 && num <= 9)
return (char)(num + '0');
else
return (char)(num - 10 + 'A');
}

void strev(char *str)
{
int len = strlen(str);
int i;
for (i = 0; i < len/2; i++)
{
char temp = str[i];
str[i] = str[len-i-1];
str[len-i-1] = temp;
}
}

char* fromDeci(char res[], int base, int inputNum)
{
int index = 0;
  
while (inputNum > 0)
{
res[index++] = reVal(inputNum % base);
inputNum /= base;
}
res[index] = '';

  
strev(res);

return res;
}

int main()
{
int inputNum, base;
   printf("Enter the decimal number: ");
   scanf("%d", &inputNum);
   printf("Enter the base to convert: ");
   scanf("%d", &base);
char res[100];
printf("Equivalent of %d in base %d is "
" %s ", inputNum, base, fromDeci(res, base, inputNum));
return 0;
}

A:
Enter the decimal number: 15                                                                                                                                                    
Enter the base to convert: 2                                                                                                                                                    
Equivalent of 15 in base 2 is  1111

B:

Enter the decimal number: 38                                                                                                                                                    
Enter the base to convert: 16                                                                                                                                                   
Equivalent of 38 in base 16 is  26

C:

Enter the decimal number: 54                                                                                                                                                    
Enter the base to convert: 6                                                                                                                                                    
Equivalent of 54 in base 6 is  130

D:

Enter the decimal number: 19                                                                                                                                                    
Enter the base to convert: 8                                                                                                                                                    
Equivalent of 19 in base 8 is  23

E:

Enter the decimal number: 27                                                                                                                                                    
Enter the base to convert: 3                                                                                                                                                    
Equivalent of 27 in base 3 is  1000
