Range of signed char and unsigned char are?
Question
Range of signed char and unsigned char are?
Solution
The range of a signed char in C/C++ is typically from -128 to 127. This is because a char is 1 byte, or 8 bits, and the first bit is used to indicate if the number is positive or negative. So, you have 7 bits left to represent the number, which gives you 2^7 = 128 possible values. Since you can have negative numbers, the range is from -128 to 127.
On the other hand, an unsigned char in C/C++ has a range from 0 to 255. Since it's unsigned, all 8 bits can be used to represent the number, giving you 2^8 = 256 possible values. But since we start counting from 0, the range is from 0 to 255.
