  • Quadratic. f(x)=x^2. D: -∞,∞ R: 0,∞
  • Reciprocal. f(x)=1/x. D: -∞,0 U 0,∞ R: -∞,0 U 0,∞ Odd.
  • Exponential. f(x)=e^x. D: -∞,∞ R: 0,∞
  • Sine. f(x)=SINx. D: -∞,∞ R: -1,1. Odd.
  • Greatest Integer. f(x)= [[x]] D: -∞,∞ R: {All Integers} Neither.

How do functions work in C language?

How function calls work in C programming language. First of all main () function of C program gets called by Operating system. Execution of C program begins. When control reaches a function call lets say myFunction (int val); it pauses the execution of current function and control goes inside the called function myFunction.

What are the basics of C language?

C language is a structured language: Structure oriented language: In this type of language, large programs are divided into small programs called functions. Prime focus is on functions and procedures that operate on the data. Data moves freely around the systems from one function to another.

Where can I define a function in C language?

Defining a Function. A function definition in C programming consists of a function header and a function body.

  • Example. Given below is the source code for a function called max ().
  • Function Declarations. A function declaration tells the compiler about a function name and how to call the function.
  • Calling a Function.

    • What are the components of C language?

    Tokens in C. A C program consists of various tokens and a token is either a keyword,an identifier,a constant,a string literal,or a symbol.

  • Semicolons. In a C program,the semicolon is a statement terminator.
  • Comments. Comments are like helping text in your C program and they are ignored by the compiler.
  • Identifiers.
  • Keywords.
  • Whitespace in C.
