(d) None of these

31. What is incorrect among the following

(b) while(!expn 1)\{if(expn 2)continue;...}
(c) do{..if(expn 1)continue;..}while(expn 2);
(d) while(!expn 2)\{if(expn 1)continue;..\}

33. Consider the following program

while(i>=0){
printf("%u",i)
i--;}
}
How many times the loop will get executed
(a)10
(b)9
(c)11

(b) calloc()
(c) free()
(d) realloc()

35.Consider the following program
main(){
int a[5]={1,3,6,7,0};
int *b;
b=&a[2];
}
The value of b[-1] is
(a) 1
(b) 3
(c) -6
(d) none

36. # define prod(a,b)=a*b
main(){

printf("%d",prod(x+2,y-10)); }
the output of the program is
(a) 8
(b) 6
(c) 7
(d) None

37.Consider the following program segment
int n,sum=1;
switch(n){
case 2:sum=sum+2;
case 3:sum*=2;

main(){
int i=3,x;
while(i>0){
x=func(i);
