How do you convert binary to hex in CPP?

To convert binary to hexadecimal just take four bits and convert it in decimal number . For example let us convert binary number (10101011)2 to hexadecimal. Note if the number is greater than 9 we write alphabets A,B,C,D,E,F in place of 10,11,12,13,14,15. (1010)2 decimal equivalent is 10 so write A.
