Ques 1. Assume that the size of an integer is 4 bytes and size of character is 1 byte. What will be the output of following program?
options :
A)12
B)16
C)8
D)4
Answer - C
Explanation : In union data type, the memory required to store a union variable is the memory required for the largest element of an union.
Ques 2. What will be the output of following program?
options :
A)9 7 5 3 1
B)9 8 7 6 5 4 3 2 1
C)Infinite loop
D)9 7 5 3
Answer - C
Explanation : The loop will run infinite time because n will never be equal to 0.
Ques 3. What will be the output of following program?
Options :
A)Geeks
B)runtime error
C)Geeksforgeeks
D)compile time error
Answer - C
Explanation : Here we are assigning(=) and not comparing(==) x with 0 which is not true so the else part will execute and print Geeksforgeeks.
Ques 4.What will be output of following c code?
Options :
A)1
B)2
C)0
D)No output
Answer : A
Explanation:
Consider the while loop condition:
i + 1 ? -- i : ++j
In first iteration:
i + 1 = 3 (True), So ternary operator will return
-–i i.e. 1
In C, 1 means true so while condition is true. Hence printf statement will print 1
In second iteration:
i + 1 = 2 (True), So ternary operator will return
-–i i.e. 0
In C, zero means false so while condition is false. Hence program control will come out of the while loop.
Ques 5. Assume that the size of an integer is 4 bytes and size of character is 1 byte. What will be the output of following program?
options :
A)12
B)16
C)8
D)4
Answer - B
Explanation : In structure data type, The amount of memory required to store a structure variable is the sum of memory size of all members.
