C Language Variables, Loops, Keyword, and Datatype Quiz

Variables in C Language

• Variables are used to store data values in C, acting as containers for data.
• A variable must be declared before it can be used, specifying its type and name.
• They can hold different types of data, including integers, floats, characters, and more.

Purpose of Loops in C Language

• Loops enable the execution of a block of code multiple times based on a specified condition.
• Common loop structures in C include for, while, and do-while loops.
• They are essential for tasks such as iteration over arrays, repeated calculations, and input/output operations.

Significance of the 'Keyword' in C Language

• Keywords are reserved words in C that have special meaning and cannot be used as identifiers for variables or functions.
• Examples of keywords include int, return, if, else, and while.
• They define the structure and flow of the C program, influencing how codes are interpreted by the compiler.

Datatype in C Language

• A datatype in C specifies the type of data that can be stored in a variable and the operations that can be performed on it.
• Common datatypes include int (for integers), float (for floating-point numbers), char (for characters), and double (for higher-precision floats).
• The choice of datatype affects memory allocation, precision, and performance within the program.
