MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A compiled program is faster to run than an interpreted program, but it takes more time to compile and run a program than to just interpret it. A compiler indeed produces faster programs. It happens fundamentally because it must analyze each statement just once, while an interpreter must analyze it each time.

Detailed explanation-2: -Interpreters usually take less amount of time to analyze the source code. However, the overall execution time is comparatively slower than compilers. Compilers usually take a large amount of time to analyze the source code. However, the overall execution time is comparatively faster than interpreters.

Detailed explanation-3: -An interpreter translates code like a compiler but reads the code and immediately executes on that code, and therefore is initially faster than a compiler. Thus, interpreters are often used in software development tools as debugging tools, as they can execute a single in of code at a time.

Detailed explanation-4: -Interpreter translates just one statement of the program at a time into machine code. Compiler scans the entire program and translates the whole of it into machine code at once. An interpreter takes very less time to analyze the source code. However, the overall time to execute the process is much slower.

Detailed explanation-5: -Compilers are sometimes confused with programs called interpreters. Although the two are similar, they differ in important ways. Compilers analyze and convert source code written in languages such as Java, C++, C# or Swift.
