Programming Languages and Compilers

When mixing signed and unsigned integers, C promotes the signed value to unsigned. -20 becomes a very large positive number (2^32-20 for 32-bit int). i+j (5 + large unsigned) exceeds 5, so the if condition is true. The printf uses %d to format j+i, which is -15 when viewed as signed. Option A is correct: >5=-15.

Function argument evaluation order in C is unspecified (typically right-to-left). The call sum(a(),b(),c()) evaluates c() first (prints 3), then b() (prints 2), then a() (prints 1). sum() adds 1+2+3=6, which printf prints. Output: 3216. The return values are used in the sum, not the print order.

The code uses assignment (=) instead of equality (). In 'if(var = true)', the assignment happens first (var becomes true), then the condition evaluates the assigned value. Since true is truthy, the if-block executes, printing 'TRUE'. This is a common bug - the programmer likely meant to compare () but accidentally assigned. There's no compilation or runtime error - Java allows boolean assignment in conditions.

An operating system is system software that manages hardware and software resources. Interpreters, compilers, and assemblers are all language translators used to convert source code into machine code.

Java is strongly typed because every variable must be declared with a type, and the compiler performs strict type checking to ensure that values assigned to variables are compatible with their declared types, preventing many runtime errors.

At the time this question was written, .NET Framework had six major version releases: 1.0, 1.1, 2.0, 3.0, 3.5, and 4.0. Note that this information is now outdated as .NET Framework has had additional releases (4.5, 4.6, 4.7, 4.8) and .NET Core/.NET 5+ represent a separate evolution.

The IHttpHandler interface in ASP.NET defines exactly two methods: ProcessRequest (which handles the HTTP request) and IsReusable (which indicates whether the handler can be pooled for reuse). Other options mention non-existent methods like ProcessResponse or GenerateRequest.

The Stream.Read(byte[], offset, count) method reads bytes from the stream into the array and returns the number of bytes actually read. Option B correctly uses this pattern. Option D writes TO the stream instead of reading from it. Options A and C use inefficient manual byte-by-byte loops.

Only option D compiles without error. Option A (float f=1.3) requires 'f' suffix or cast because 1.3 is double by default. Option B (char c="a") uses double quotes instead of single quotes. Option C (byte b=257) exceeds byte's max value (255).

When you run java myprog good morning, the argv array has only 2 elements: argv[0]="good" and argv[1]="morning". Accessing argv[2] causes ArrayIndexOutOfBoundsException because index 2 doesn't exist.

When i=1, case 1 matches and prints "one". Since there's no break statement, execution "falls through" to case 2 (prints "two") and then to default (prints "default"). Fall-through is a deliberate (and sometimes useful) feature in Java switch statements.

The | operator performs bitwise OR: 4 (binary 100) OR 3 (binary 011) = 111 (binary) = 7 (decimal). Each bit position is set to 1 if either operand has a 1 in that position.

In older versions of SSIS (SQL Server 2005), VB.Net was the only supported language for the Script Component. Modern versions support both VB.Net and C#, making the question version-dependent.

To create a read-only property in VB.NET, you use the ReadOnly modifier and define only the Get block within the property block, omitting the Set block.

Java 5 introduced autoboxing, which automatically converts primitive int to Integer when adding to a List. The code compiles without error because the compiler handles the conversion from primitive 5 to Integer object automatically.
