5) Macros and functions do not differ in the following respects
a] type checking b] vqariable number of arguments c] recursion
d]declaration of local variables
6]what is the value assigned to a and b when the following piece of ‘C’
code is executed

if(y
printf(“3”);
}
what is printed when this program is executed
a] 1 3 b] 2 3 c] 3 d] 2
14)the declaration of a variable does not result in one of the following
a] knowing the type of the variable
b] knowing the size of the variable
c] knowing the scope of the variable
d] allocation of storage space for the variable
15)a goto statement can reference a label
a] in another function within the same file
b] in another function in a different file
c] within the same function
d] none of the above
16)the body of the loop of which of the following loop constructs
