Can U debug?? just (C) try this...

1.What is the output?

enum colors {BLACK,BLUE,GREEN};
main(){
  printf("%d..%d..%d",BLACK,BLUE,GREEN);
  return(1);}
         
A.. 0..1..2                                                                                                                           

 B. 1..2...3

C. Will not compile

2. Predict the output

#define int char
main(){
            int i=65;
            printf("sizeof(i)=%d",sizeof(i));}

A. sizeof(i)=1

B. sizeof(i)=65

C sizeof(i)=2

3. Judge the output

#define square(x) x*x
main(){
int i;
i = 64/square(4);
printf("%d",i);}

A..4                B.64      
 C.Compilation error

4. Does the following program generate error?

 #include<stdio.h>
#define a 10
main(){
#define a 50
printf("%d",a);}
A. Yes               B. No
           

5.What is the output

#define f(g,g2) g##g2
main(){
          int var12=100;
          printf("%d",f(var,12));
}

A. Compilation error                                                                                                                   B.100                                                                                                                                                    C.12
