Unsigned addition and overflow

Convert each of the operands $($unsigned decimal values$),$ in I. and in II$.$ below, into its corresponding binary value $($w $=8),$ then perform both the decimal addition and the binary addition, indicating the true sum and the actual sum and whether these two sums are the same or not.

Unsigned addition:

I. $74+63$

II$.123+157$

For the binary addition, clearly label all carry in bits $($by using the label carry in$)$ and the carry out bit $($by using the label carry out$).$

Also indicate whether or not an overflow occurred.

Finally, explain how addition overflow can be detected, in general, when adding operands that have unsigned decimal values in a C program where you do not have access to the carry out bit $($this means that you cannot use a larger data type to store the resulting sum$).$
