[C] Three Five Seven Odd
[D] Three Five Seven
सही उत्तर: Three Five Seven Odd
व्याख्या: Case 3 से Execution शुरू होकर Break न होने के कारण सभी अगले Cases तथा Default Execute होंगे।
Correct Answer: Three Five Seven Odd
Explanation: Execution falls through from case 3 to case 5, case 7 and default.
73. दिए गए Union Program का Output क्या होगा?
[A] 8
[B] 6
[C] 10
[D] 14
73. What will be the output of this program?
[A] 8
[B] 6
[C] 10
[D] 14
सही उत्तर: 8
व्याख्या: Union का Size उसके सबसे बड़े Member के Size के बराबर होता है। double सामान्यतः 8 bytes का होता है।

74. दिए गए Program में X का मान क्या होगा?
[A] X=4
[B] X=20
[C] X=25
[D] X=10
74. What will be the output of this program?
[A] X=4
[B] X=20
[C] X=25
[D] X=10
सही उत्तर: X=4
व्याख्या: i = 0,5,10,15 पर X बढ़ता है, इसलिए X का अंतिम मान 4 होगा।
Correct Answer: X=4
Explanation: X is incremented when i is 0, 5, 10 and 15, so the final value is 4.
75. दिए गए Program का Output क्या होगा?
[A] X=30
[B] X=20
[C] X=25

75. What will be the output of the above program?
[A] X=30
[B] X=20
[C] X=25
[D] X=10
सही उत्तर: X=30
व्याख्या: i=0,5,10,15 पर X में जोड़ होता है: 0+5+10+15=30।
Correct Answer: X=30
Explanation: The values 0, 5, 10 and 15 are added, resulting in X=30.
