1. State whether the following are valid statements. If they are not. Assume variables, a, b & c are declared as integer variables and have been given values (a = 5, b = 10, c = 12) prior to each of the following statements. If they are valid explain what the statement will do. (3 points each)
a) if (a = (b == c)) a = 1; else a = -1;
b) a += b ++;
c) (a - b) = c;
d) a = (b - 1) ? b : c;
e) a += b == c;
f) a-=1;
g) a=-1;
h) b ** b;
i) int x [a];
j) a = —a - -;
k) unsigned char m = 5;
l) a * = ++ b;
m) b++ = a;
n) a += b++ + ++c;
o) char N [ ];
p) char L [ ] — *abcd”;

6. Write a loop to print all integers that are multiples of eleven between 1 and 1000. (5 pts)
7. Write a loop which will: (10 pts Read a character from the keyboard Print a message telling if the character is a digit, uppercase, or lowercase If the character is a lowercase x the loop will terminate, otherwise it reads another character. 8. Write the declaration for a variable called string holding a string up to 25 alphabetic characters (2 pts) 9. Write a piece of code using only one switch and no other control structures to read one character and do the following: (10 pts) if a 1 print “Got a ONE if a 3 print “Got a THREE if a 5 print “Got a FIVE” if a 7 print “Got a SEVEN” if a 9 print “Got a NINE” if an even number print “Got an even number” if a non-digit print “Got a non-digit” 10. Write a section of code that will take an integer variable Y and if Y is negative, will set to zero. If Y is greater than zero, the code will add one to Y if and only if Y is also an even number (5 pts)
