Show that the following program running on Pentium prints

fff0 f0

fffffff0 f0

========== Program =================

#include

void main() {

char c;

unsigned char uc;

short s1, s2;

unsigned short us1, us2;

c = 0xf0; uc = 0xf0;

us1 = c; us2 = uc;

printf("us1 = %8x,\tus2 = %8x ", us1, us2);

s1 = c; s2 = uc;

printf("us1 = %8x,\tus2 = %8x ", s1, s2);

}

Show the following steps:

Step1 show the values in c and uc

Step2 show the integral promoted values of c and uc

Step3 show the values in us1 and us2

Step4 show the integral promoted values of us1 and us2

(these are the values printed by the first printf statement)

Step5 show the integral promoted values of c and uc

(they are the same as those values in Step2)

Step6 show the values in s1 and s2

Step7 show the integral promoted values of s1 and s2

(these are the values printed by the second printf statement)
