5. Memory Layout Given the C struct definition below struct Simplestruct { int i; char c; double d; unsigned char a[11]; float f; }; struct Simplestruct ssp; Assume that int's are 4 bytes and have 4 byte alignment and that double has 8 byte alignment and float has 4 byte alignment. if calling printf("$x\n",ssp) yields CA028, what is the address of each field? You should express the answers in hexadecimal. &ssp->i = &ssp->c = &ssp->d = &ssp->a = &ssp->f =
