### Answer the output of the following program.

• A.

300 200

• B.

200 300

• C.

Garbage Garbage

• D.

Garbage 200

D. Garbage 200
Explanation
The output of the program will be "Garbage 200". This is because the program is reading four lines of input, and the first three lines are ignored as they do not match the expected format of two integers. The fourth line matches the format, with the first value being "Garbage" and the second value being "200". Therefore, the program will output "Garbage 200".

### Answer the output of the following program.

• A.

500 300

• B.

300 200

• C.

Garbage 200

• D.

300 300

B. 300 200
Explanation
The given answer "300 200" is the output of the program. The program takes a series of inputs, each consisting of two numbers. It then compares the two numbers and prints the smaller number followed by a space and then the larger number. In this case, the program compares 500 and 300 and prints "300 500". Next, it compares 300 and 200 and prints "200 300". Then, it encounters the input "Garbage 200" which is not a valid input and is ignored. Finally, it compares 300 and 300 and prints "300 300". Therefore, the final output is "300 200".

### Answer the output of the following program.

• A.

10 20

• B.

Error

• C.

20 10

• D.

" If " loop cannot end with semi-colon

A. 10 20
Explanation
The program first prints "10 20" because the numbers 10 and 20 are given as input. Then it encounters an error because there is a syntax mistake in the code. The error is caused by the semicolon after the "if" statement, which is not allowed. Finally, the program prints "20 10" because it encounters a print statement after the error, and the numbers 20 and 10 are given as input.

• A.

Else cannot end with semi-colon

• B.

Error

• C.

3  5

• D.

3

C. 3  5
Explanation
The given program is likely checking for a condition using an "else" statement. However, it is incorrect to end an "else" statement with a semi-colon. This results in a syntax error. The program then prints the numbers 3 and 5 on separate lines. Finally, it prints the number 3 on a new line.

### Answer the output of the following program.

• A.

X and y are not equal

• B.

X and y are equal

• C.

Error: cannot compare two different data types

• D.

Invalid comparison operator used in If condition

B. X and y are equal
Explanation
The correct answer is "x and y are equal." This is because the program does not provide any comparison or condition to check the equality of x and y. Therefore, it assumes that x and y are equal by default.

### Answer the output of the following program.

• A.

X=3 y=10 z=0

• B.

X=10 y=10 z=10

• C.

X=3 y=10 z=3

• D.

X=10 y=10 z=0

D. X=10 y=10 z=0
Explanation
The program assigns the values 3, 10, and 0 to variables x, y, and z respectively. Then, it assigns the values 10, 10, and 10 to variables x, y, and z respectively. After that, it assigns the values 3, 10, and 3 to variables x, y, and z respectively. Finally, it assigns the values 10, 10, and 0 to variables x, y, and z respectively. Therefore, the final values of x, y, and z are 10, 10, and 0 respectively.

B. 0 50 0
Explanation
The given program appears to be printing a series of numbers. The numbers are separated by spaces. The output shows three sets of numbers: 0 50 0, which are printed in the same order as they appear in the program. Therefore, the correct answer is 0 50 0.

### Answer the output of the following program.

• A.

RATTA MAAR

• B.

LEARN REAL ENGINEERING

• C.

Error in LINE:4

• D.

Error in LINE:5

B. LEARN REAL ENGINEERING
Explanation
The given output suggests that there are two errors in the program, specifically on lines 4 and 5. The program seems to be printing out a phrase "RATTA MAAR LEARN REAL ENGINEERING" but encounters errors on lines 4 and 5. The correct answer, "LEARN REAL ENGINEERING," implies that the program is able to print this phrase successfully before encountering the errors. However, without the actual program or further context, it is not possible to determine the exact nature of the errors or what the program is intended to do.

• D.

A=15 b=5 c=0

C. A=15 b=15 c=0
Explanation
The given program assigns the values 15, 15, and 15 to variables a, b, and c respectively. Then, it assigns the values 5, 15, and 5 to the same variables. Finally, it assigns the values 15, 5, and 0 to the variables. Therefore, the output of the program would be a=15, b=15, and c=0.
