convert string to unsigned int

Hello, if I put the value of the last bit (bit 31) to 1, the value becomes negative.

I want to convert the value to unsigned.

How should I do it?.

Here you can see a variable of 32 bits that has its first bit to 1 and its last bit also to 1.

You can see the unsigned value and the negative signed value, they are different values.

I want to get only unsigned but C2 does not cast unsigned.

add (the amount of characters in the variable ^ 2) /2
