int input1, input2;
int result;
cin >> input1;
cin >> input2;
result = ComputeNum(input1, input2);
cout << result << endl;
return 0;
Explanation:
Answer:
3e : 00111110 (62)
3e0 : 0000001111100000 (992)
3e00 : 0011111000000000 (15872)
Explanation:
Converting the given hexadecimal numbers to binary and decimal format:
1) 3e
3-> 0011
e-> 1110
Combining , 3e -> 00111110
This can be converted to decimal by multiplying each 1 in the binary representation by 2^(position -1) and adding the results.
So 3e = 32+16+8+4+2 = 62
2) 3e0
Binary => 0000001111100000
Converting to decimal : 992 [ This is 16 times a]
3) 3e00
Binary => 0011111000000000
Converting to decimal : 15872 [ This is 16 times b]
So adding a 0 to the hex representation multiplies the decimal number by 16.
