#include <stdio.h>

hexadecimal conversions

void tohex (int num)

{

int temp;

Char Chs[8]; //define a temporary container with a length of 8,8x4=32 bit bits

int pos=8; //define an index

Char ch[] = {' 0 ', ' 1 ', ' 2 ', ' 3 ',

' 4 ', ' 5 ', ' 6 ', ' 7 ',

' 8 ', ' 9 ', ' A ', ' B ',

' C ', ' d ', ' e ', ' f '};

printf ("Hexadecimal of%d is:", num);

while (num!=0)

{

temp = num & 15;

Chs[--pos]= Ch[temp]; //The data in the table is stored in a temporary container.

num = num >> 4; //Move left four bit lower

};

for (int x=pos;x<8;x++)

{

printf ("%c", chs[x]);

}

printf ("\ n");

}

Octal conversions

void tooct (int num)

{

int temp;

Char chs[11]; //define a temporary container

int pos=11; //define an index

Char ch[] = {' 0 ', ' 1 ', ' 2 ', ' 3 ',

' 4 ', ' 5 ', ' 6 ', ' 7 ',

' 8 ', ' 9 ', ' A ', ' B ',

' C ', ' d ', ' e ', ' f '};

printf ("%d octal is:", num);

while (num!=0)

{

temp = num & 7;

Chs[--pos]= Ch[temp]; //The data in the table is stored in a temporary container.

num = num >> 3; //Move left three bit lower

};

for (int x=pos;x<11;x++)

{

printf ("%c", chs[x]);

}

printf ("\ n");

}

Conversion of binary binary

void tobinary (int num)

{

int temp;

Char chs[32]; //define a temporary container

int pos=32; //define an index

Char ch[] = {' 0 ', ' 1 ', ' 2 ', ' 3 ',

' 4 ', ' 5 ', ' 6 ', ' 7 ',

' 8 ', ' 9 ', ' A ', ' B ',

' C ', ' d ', ' e ', ' f '};

printf ("%d binary is:", num);

while (num!=0)

{

temp = num & 1;

Chs[--pos]= Ch[temp]; //The data in the table is stored in a temporary container.

num = num >> 1; //Move left one bit lower

};

for (int x=pos;x<32;x++)

{

printf ("%c", chs[x]);

}

printf ("\ n");

}

int main (int argc, const char * argv[])

{

Tohex (60);

TOOCT (60);

Tobinary (60);

printf ("\ n");

return 0;
