In a TC++ compiler, the binary representation of 5 is (00000000000000101). I know that negative numbers are stored as 2's complement, thus -5 in binary is (111111111111011). The most significant bit (sign bit) is 1 which tells that it is a negative number.

So how does the compiler know that it is -5? If we convert it normally, like from decimal to binary, it gives us some other number.

And why is 1's compliment of 5 -6 (1111111111111010)?

In a TC++ compiler, the binary representation of 5 is (00000000000000101). I know that negative numbers are stored as 2's complement, thus -5 in binary is (111111111111011). The most significant bit (sign bit) is 1 which tells that it is a negative number.

So how does the compiler know that it is -5? If we interpret the binary value given above (111111111111011) as an unsigned number, it will turn out completely different?

Also, why is the 1's compliment of 5 -6 (1111111111111010)?

in a TC++ compiler binary representation of 5 is (00000000000000101) and i know that negative no. is stored as 2's compliment thus -5 in binary is (111111111111011) most significant bit(sign bit) is 1 which tells that it is a negative no. so how does the compiler knows that it is -5 i mean if we convert it normally like from decimal to binary it gives us some other no. and how does 1's compliment of 5 is -6 (1111111111111010)  ? thanks.....
