Assembler is a program that translates the program from

Since the interpreter translates the program line-by-line, it takes more time than the compiler to translate. Programs converted through interpreters are not completely converted into machine or object programs. Translation is required every time the program is executed. Do not generate output program. So they evaluate the source program at every time during execution.

Assembler is a translator program which is used to translate the assembly language code into machine language code. Functions of assembler:.

Convert mnemonic codes into equivalent machine code. Convert symbolic operands or address to machine addresses. Keep all instructions and data in main memory. If there is any error in program, notify with error message. Informing the program control after correcting all the errors in the program etc. The difference between an interpreter and a compiler is given below:.

Knowledge Based Questions:. Go for Answer. Comprehension Based Questions:. Creative Questions:. Read the stem and answer the questions:. Arafat and Nila are two programmers. Arafat writes programs with the help of various mnemonics. Programs written by two of them can solve the same problem. Rahim and Karim are programmers. They follow two different programming approaches to write programs. Kabbo on the other hand uses different English words to write programs.

Give analytical feedback. Multiple Choice Questions:. Translates the entire program at once. Debugging and testing in the program is faster.

If there is error displays it on the monitor. Which translator program is used for C programming language? In case of program translation. Written by,. Your email address will not be published.

A cross-compiler running on a Windows machine, for instance, could generate code that runs on a specific Windows operating system or a Linux operating system platform.

Source-to-source compilers translate one program, or code, to another of a different language e. Choosing a compiler then, means that first you need to know the ISA, operating system, and the programming language that you plan to use. Compilers often come as a package with other tools, and each processor manufacturer will have at least one compiler or a package of software development tools that includes a compiler.

Often the software tools including compiler are free; after all, a CPU is completely useless without software to run on it. Compilers will report errors after compiling has finished. Interpreters Another way to get code to run on your processor is to use an interpreter, which is not the same as a compiler. 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. Compilers translate code all at once and the processor then executes upon the machine language that the compiler produced.

If changes are made to the code after compilation, the changed code will need to be compiled and added to the compiled code or perhaps the entire program will need to be re-compiled. There are several types of interpreters: the syntax-directed interpreter i. Assembler is A. Join The Discussion.

Allocate space in memory for the programs and resolve symbolic references between object decks B. Physically place the machine instructions and data into memory C. Adjust all address dependent locations, such as address constants, to correspond to the allocated space D. All of the above.
