Problem $1.$ The C$99$ version of the C Language Standard introduced "exact$-$width" integer types int$8\_$t$,$ int$16\_$t$,$ int$32\_$t and int$64\_$t$,$ which are available if and only if they are natively supported $-$ that is$,$ if the hardware can deal with signed integers with those sizes $($i$.$e$.,8,16,32,64$ bits respectively$).$ These types, along with unsigned counterparts uint $8,16,32,61$ are declared in the header file stdint.h$.$ For each of the following declarations, give a declaration using standard types $($i$.$e$.,$ int, unsigned int, unsigned char, etc.$)$ that results in the variable foo having the same size $($and number of elements, for an array$)$ as in the original declaration.

a$.$ uint$16\_$t foo;

b$.$ int$32\_$t foo;

c$.$ uint$64\_$t foo;

d$.$ int$8\_$t foo $[128]$ ;
