1100
0xc = 1100 Hexadecimal digits use exactly 4 binary digits (bits). The 0x0 to 0xf of hexadecimal map to 0000 to 1111 of binary. Thinking of the hexadecimal digits as decimal numbers, ie 0x0 to 0x9 are 0 to 9 and 0xa to 0xf are 10 to 15, helps with the conversion to binary: 0xc is 12 decimal which is 8 + 4 → 1100 in [4 bit] binary.
The answer is 1100.

No, it can be done in C.
binary language
The hexadecimal value 0xCA can be converted to binary by converting each hex digit to its 4-bit binary equivalent. The hex digit 'C' corresponds to the binary 1100, and 'A' corresponds to 1010. Therefore, the binary representation of 0xCA is 11001010.

write a c++ program to convert binary number to decimal number by using while statement
To send the ASCII representation of the expression "a3c2," you would convert each character into its corresponding ASCII value. The ASCII values are: 'a' (97), '3' (51), 'c' (99), and '2' (50). You can send these values as a sequence of numbers or convert them to binary or hexadecimal if needed. For example, in binary, "a3c2" would be represented as 01100001 00110011 01100011 00110010.
A = 1010 b = 1011 c = 1100
