C is a high-level high-level In computer science, a high-level programming language is a programming language with strong abstraction from the details of the computer https://en.wikipedia.org › High-level_programming_language and general-purpose programming language that is ideal for developing firmware or portable applications Originally intended for writing system software, C was developed at Bell Labs by Dennis Ritchie for the unix operating system in the early 1970s.
What do you mean by C language?
C is an imperative procedural language supporting structured programming, lexical variable scope, and recursion, with a static type system It was designed to be compiled to provide low-level access to memory and language constructs that map efficiently to machine instructions, all with minimal runtime support.
Why is C called C?
After language ‘B’, Dennis Ritchie came up with another language which was based upon ‘B’. As in alphabets B is followed by C and hence he called this language as ‘C’.
What is C language with example?
C language is a system programming language because it can be used to do low-level programming (for example driver and kernel) It is generally used to create hardware devices, OS, drivers, kernels, etc. For example, Linux kernel is written in C. It can’t be used for internet programming like Java,Net, PHP, etc.
What is the C language written in?
C started with the BCPL language , Ken Thomson had access to a compiler for it that ran on their General Electrics 635 main frame. Unhappy with the language, Thomson used BCPL to write a compiler for the B language, an evolutionary step beyond BCPL that removed some of the technical problems in BCPL.
What is C compiler?
compiler, computer software that translates (compiles) source code written in a high-level language (e.g., C++) into a set of machine-language instructions that can be understood by a digital computer’s CPU. Compilers are very large programs, with error-checking and other abilities.
What is data type in C?
In C programming, data types are declarations for variables This determines the type and size of data associated with variables. For example, int myvar; Here, myVar is a variable of int (integer) type.
What is History of C?
C is one of the high-level programming languages developed by Dennis Ritchie C was originally developed for UNIX operating system to beat the issues of previous languages such as B, BCPL, etc. The UNIX operating system development started in the year 1969, and its code was rewritten in C in the year 1972.
What level is C?
C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs.
Why do we use in C?
It is used for preprocessor directives (#include, #if, #else, #elif, #endif, #define, #undef, #error, #ifdef, #ifndef, # (null directive), #pragma) as well as the stringizing operator ‘#’ and the token pasting operator ‘##’.
What is the importance of C?
C is called as a robust language, which has so many built-in functions and operations, which can be used to write any complex program Generally, we use to call C as a middle level language. Because, the ‘C’ compiler combines the capabilities of an assembly language with the features of a high-level language.
How do you write C code?
- #include <stdio. h>
- int main(){
- printf(“Hello C Language”);
- return 0;
- }
Why C is mother of all languages?
1) C as a mother language ? C language is considered as the mother language of all the modern programming languages because most of the compilers, JVMs, Kernels, etc. are written in C language, and most of the programming languages follow C syntax , for example, C++, Java, C#, etc.
What is array in C?
Array in C can be defined as a method of clubbing multiple entities of similar type into a larger group These entities or elements can be of int, float, char, or double data type or can be of user-defined data types too like structures.
When was C written?
C was developed in the early 1970s by Ken Thompson and Dennis Ritchie at Bell Labs. It is a procedural language, which means that people can write their programs as a series of step-by-step instructions.
Why was C invented?
The C language was actually created to move the UNIX kernel code from assembly to a higher level language , which would do the same tasks with fewer lines of code. Oracle database development started in 1977, and its code was rewritten from assembly to C in 1983. It became one of the most popular databases in the world.
When was C created?
C, computer programming language developed in the early 1970s by American computer scientist Dennis M. Ritchie at Bell Laboratories (formerly AT&T Bell Laboratories).

What is main () in C language?
A main() function is a user-defined function in C that means we can pass parameters to the main() function according to the requirement of a program. A main() function is used to invoke the programming code at the run time, not at the compile time of a program.
Why is C so popular?
The C programming language is so popular because it is known as the mother of all programming languages This language is widely flexible to use memory management. C is the best option for system level programming language.
What are pointers in C?
A pointer is a variable that stores the memory address of another variable as its value A pointer variable points to a data type (like int ) of the same type, and is created with the * operator.
What is source code in C?
Source code is generally understood to mean programming statements that are created by a programmer with a text editor or a visual programming tool and then saved in a file object code generally refers to the output, a compiled file, which is produced when the Source Code is compiled with a C compiler.
What is an algorithm in C?
An algorithm is a procedure or step-by-step instruction for solving a problem They form the foundation of writing a program. For writing any programs, the following has to be known: Input. Tasks to be preformed.
What is byte in C?
A byte is typically 8 bits C character data type requires one byte of storage. A file is a sequence of bytes. A size of the file is the number of bytes within the file. Although all files are a sequence of bytes,m files can be regarded as text files or binary files.
What is double in C?
A double is a data type in C language that stores high-precision floating-point data or numbers in computer memory It is called double data type because it can hold the double size of data compared to the float data type. A double has 8 bytes, which is equal to 64 bits in size.
What are tokens in C?
One can define tokens in C as the smallest individual elements in a program that is meaningful to the functioning of a compiler A token is the smallest unit used in a C program. Each and every punctuation and word that you come across in a C program is token.
What are features of C?

What is C character set?
In the C programming language, the character set refers to a set of all the valid characters that we can use in the source program for forming words, expressions, and numbers The source character set contains all the characters that we want to use for the source program text.
What does Level C mean in reading?
