High level languages and natural language

Short answer

High-level languages resemble natural language through English keywords like 'if', grammar with structured statements and semicolons, and mathematical expressions like 'area = 3.14 * r * r'. Variables can be named meaningfully. Unlike natural language, they are exact and unambiguous.

How high level programming languages are similar to natural language? Describe.

High-level languages are designed so that programmers can write instructions in a form close to human language. The similarities are:

  • Vocabulary: they use English words as keywords, such as if, else, while, for, return, print.
  • Grammar (syntax): like a sentence structure, statements must follow fixed rules, for example if (a > b) ... else ... reads like "if a is greater than b, then ... otherwise ...".
  • Punctuation: statements end with a symbol (;) like a full stop, and blocks use { } or brackets like paragraphs.
  • Meaning (semantics): every valid statement has a definite meaning, just as a sentence does.
  • Mathematical notation: expressions like area = 3.14 * r * r are close to normal mathematics.
  • Names: variables can be given meaningful words (total_marks, salary).

Unlike a natural language, however, a high-level language is exact: it has no ambiguity, and a small syntax mistake gives an error.
