1. (a) On a 32-bit machine, a variable of type float is _____ bytes in size. (b) On a 32-bit machine, the following struct a is _____ bytes in size. struct a { int x; double y; }; (c) What is the value of NULL? (d) What C function concatenates one array of characters to the end of another array of characters? 2. The output of the following program is : M E CS Please fill in the blanks : #include<stdio.h> #include<stdlib.h> #include<string.h> struct a{ char as1[2]; char as2[2]; }; struct b{ char bs1; char bs2; char bs3[2]; }; int main(){ ____________ p1 = malloc(_______________); struct b p2; strcpy(p1->as1,strdup("ME")); strcpy(p1->as2,strdup("CS")); memcpy(&_________, p1, _______________); p2.bs3[2]='\0'; printf("%c\n", p2.bs1); printf("%c\n", p2.bs2); printf("%s\n", p2.bs3); return 0; } 3. The dot product of two vectors is computed by the following formula: sum {from i=1 to n} a_i * b_i For instance, if a = [1 2 3] b=[4 5 6]
