What will be the output of the program?
#include
A.
FresherGATE... |
B.
FresherGATE... FresherGATE... |
C.
Error: cannot use control instructions in macro |
D.
No output |
Answer : Option B
Explanation :
The macro FUN(arg) prints the statement "IndiaBIX..." untill the while condition is satisfied.
Step 1: int i=2; The variable i is declared as an integer type and initialized to 2.
Step 2: FUN(i becomes,
do { if(2 3) printf("IndiaBIX...", "\n"); }while(--2)
After the 2 while loops the value of i becomes '0'(zero). Hence the while loop breaks.
Hence the output of the program is "IndiaBIX... IndiaBIX..."
