MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A compiler is a special program that translates a programming language’s source code into machine code, bytecode or another programming language. The source code is typically written in a high-level, human-readable language such as Java or C++.

Detailed explanation-2: -Compilers convert high-level language code to machine (object) code in one session. Compilers can take a while, because they have to translate high-level code to lower-level machine language all at once and then save the executable object code to memory.

Detailed explanation-3: -It converts a high-level language program into machine language line by line as well as executes it. If there is any error in the program, translation and execution stops and the error is reported for debugging.

Detailed explanation-4: -A compiler is a translator program that converts a high-level language source program into a machine language object program.

Detailed explanation-5: -A high-level language is a programming language that uses English and mathematical symbols in its instructions. To execute a program in a high-level language, it can be compiled or interpreted. A compiler translates the entire program written in a high-level language to machine language prior to execution.
