What is the most significant contribution of Grace Hopper?

What is the most significant contribution of Grace Hopper?

While working for Eckert-Mauchly Computer Corporation in the 1950s, Hopper invented the compiler, a program that simplified computer language. The compiler is perhaps her most well-known contribution to the world of computer science, an invention she said she created because she was lazy.

How did Grace Hopper impact the world?

Hopper was involved in the creation of UNIVAC, the first all-electronic digital computer. She invented the first computer compiler, a program that translates written instructions into codes that computers read directly. This work led her to co-develop the COBOL, one of the earliest standardized computer languages.

Who found the first computer bug?

Grace Hopper

Why is Grace Hopper important?

Grace Brewster Murray Hopper (1906-1992) was a computer pioneer and naval officer. Hopper is best known for her trailblazing contributions to computer programming, software development, and the design and implementation of programming languages.

Who created the first compiler?

Corrado Böhm

Who invented Flowmatic in 1953?

What language are assemblers written in?

assembly language

Are compilers written in assembly?

A very simple compiler can be written from an assembler and machine code. Once you have a software that is able to translate something into binary instructions, you can use the original compiler to write a more sophisticated one (then use a second further refined one to write a third and so on).

What language is GCC written in?

C

What language is C++ written in?

Before the initial standardization in 1998, C++ was developed by Danish computer scientist Bjarne Stroustrup at Bell Labs since 1979 as an extension of the C language; he wanted an efficient and flexible language similar to C that also provided high-level features for program organization.

Why compiler is faster than interpreter?

Compilers usually take a large amount of time to analyze the source code. However, the overall execution time is comparatively faster than interpreters. No intermediate object code is generated, hence are memory efficient. Generates intermediate object code which further requires linking, hence requires more memory.

Why is Python so slow?

Python is slower than C because it is an interpreted language. This amplifies the number of actual CPU instructions required in order to perform a given statement. The difference is that the python code will be interpreted, instead of directly by the CPU.

What are the disadvantages of an interpreter?

The biggest disadvantage is speed. Interpreted code runs slower than compiled code. This is because the interpreter has to analyse and convert each line of source code (or bytecode) into machine code before it can be executed.

Which code will run faster using an interpreter?

Compiler transforms code written in a high-level programming language into the machine code, at once, before program runs, whereas an Interpreter coverts each high-level program statement, one by one, into the machine code, during program run. Compiled code runs faster while interpreted code runs slower.

Is interpreter a translator?

An interpreter is a person specially trained to convert oral messages from one language to another. A translator is a person specially trained to convert written text from one language to another. Translators and interpreters are agents in creating understanding between people.

Is Python interpreted language?

For the most part, Python is an interpreted language and not a compiled one, although compilation is a step. Python code, written in . py file is first compiled to what is called bytecode (discussed in detail further) which is stored with a . pyc or .

Is C an interpreted language?

The code of compiled language can be executed directly by the computer’s CPU. A program written in an interpreted language is not compiled, it is interpreted. Example of compiled language – C, C++, C#, CLEO, COBOL, etc. Example of Interpreted language – JavaScript, Perl, Python, BASIC, etc.

Why C is a compiler language?

It is a procedure and structure oriented language. It has the full support of various operating systems and hardware platforms. Many compilers are available for executing programs written in ‘C’. A compiler compiles the source file and generates an object file.

Why C is called a compiled language?

C is what is called a compiled language. This means that once you write your C program, you must run it through a C compiler to turn your program into an executable that the computer can run (execute). A widely used commercial compiler is Microsoft’s Visual C++ environment (it compiles both C and C++ programs).

Is Python easier than Java?

There is more experimentation than production code. Java is a statically typed and compiled language, and Python is a dynamically typed and interpreted language. This single difference makes Java faster at runtime and easier to debug, but Python is easier to use and easier to read.

Can Python replace Java?

Many programmers have proved that Java is faster than Python. They have to replace Python’s default runtime with CPython, PyPy or Cython to increase the execution speed significantly. On the other hand, the performance of the Java application can be easily optimized without using any additional tools.

Is Python built on C?

Python is written in C (actually the default implementation is called CPython). Python is written in English. But there are several implementations: CPython (written in C)

Is Python written in PHP?

Python and PHP are very similar. Both are object-oriented interpreted languages that run on a variety of operating systems. They’re both dynamically typed and have terrific IDE support. Lastly, Python and PHP both stand out in the world of syntax.

Is C++ better than Python?

The performance of C++ and Python also comes to an end with this conclusion: C++ is much faster than Python. After all, Python is an interpreted language, and it cannot be a match for a compiled language such as C++. The good news is that you can get the best of both worlds by combining C++ and Python code.

Who is father of Python?

Guido van Rossum
