C LANGUAGE Flashcards
Who invented C programming language
Dr. Dennis Ritchie
considered as a middle-level programming language because it combined the power of low-level language (such as Assembly language) and the elegance of high-level language like Pascal.
C language
are programs embedded inside Integrated Circuits (IC) or chips..
Embedded intelligence systems
do not provide all the built-in functions found in high-level languages, but to provide all building blocks needed to produce the result desired. Examples: C, C++
Middle-Level languages
provide almost everything that the programmer might need to do as already built into the language. Example: Java, Python
High-Level languages
provide nothing other than access to the machines basic instruction set. Example: Assembler
Low-Level languages
This is a preprocessor command that includes a standard input-output header file from the C library before compiling a C program.
include <stdio.h></stdio.h>
This is the main function from where the execution of any C program begins
int main()
This indicates the beginning of the main function.
{
- whatever is given inside the command “/* */” in any C program, won’t be considered for compilation and execution.
*/ */
command prints the output onto the screen.
printf
This command waits for any character input from the keyboard.
getch(); / getche();
- This command terminates C program (main function)
return 0
This indicates the ending of the main function
}
is a macro preprocessor (allows you to define macros) that transforms programs before it is compiled. These transformations can be included such as in a header file. It usually starts with a (#) pound sign.
