Why is C language important?
So, learning ‘C’ as the main language will play an important role while studying other programming languages. It shares the same concepts such as data types, operators, control statements and many more. ‘C’ can be used widely in various applications. It is a simple language and provides faster execution.
What is main function in C?
Every C program has a primary (main) function that must be named main. The main function serves as the starting point for program execution. It usually controls program execution by directing the calls to other functions in the program.
What is cout in C programming?

What is the compiler in C?
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 count in C?
The counting loop contained in count1.c is. printf(“The integers from 1 up to %d are:\n”, limit); i = 1; while (i <= limit) { printf(“%d “, i); i = i + 1; } printf(“\n”); A counting loop typically uses a variable to count from some initial value to some final value. This variable is often called the index variable.
What is the basic syntax of C?
The C basic syntax consists of header files, main function, and program code. This is the most fundamental structure in the C program. A C program necessarily consists of the main function because the execution of the program starts from this line. Without the main function, the program execution does not start.
What is the purpose of & in C?
“*” Operator is used as pointer to a variable. Example: * a where * is pointer to the variable a. & operator is used to get the address of the variable. Example: &a will give address of a.
What is scanf in C?

What are operators in C?
An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. C language is rich in built-in operators and provides the following types of operators − Arithmetic Operators. Relational Operators.
What are arrays in C?
An array is a collection of data items, all of the same type, accessed using a common name. A one-dimensional array is like a list; A two dimensional array is like a table; The C language places no limits on the number of dimensions in an array, though specific implementations may.
What does & mean in C?

What is the concept of C programming?
C is a procedural programming language. The main features of C language include low-level access to memory, simple set of keywords, and clean style, these features make C language suitable for system programming like operating system or compiler development.
What is the use of C language?
