Q.3 What is the following program doing?

main ()

{ int d = 1;

do

printf(“%d\n”, d++);

while (d < = 9);}

(A) Adding 9 integers (B) Adding integers from 1 to 9

(C) Displaying integers from 1 to 9 (D) None of these

Ans: C

d starting from 1 is incrementing one by one till d=9 so the printf statement is printing

numbers from 1 to 9.
