Write a C program to display ranges of all data types in tabular form
The different data types we use in C programming include integers, shorts, signed and unsigned characters, etc.
Data Type
Data type specifies the collection of values and the data type that can be stored in a variable. They allow the programmer to choose the type that suits the application's needs.
The data types are as follows-
- Main data types
- Derived data types
Let us understand the main type of data.
Main data types
' The C' compiler supports four basic data types. They are mentioned below -
- Integer
- Character
- Floating Point - Point
- Double Precision Floating Point
Integer data type
The integer data type is used to store integers and characters. It is further divided into -
- Integer data types.
- Character data type.
Integer data type
This data type is used to store integers. It has three types of integer storage, namely short, integer and long in signed and unsigned forms.
Range | |||
---|---|---|---|
Short (or) signed short | 1 | -128 to 127 | |
Unsigned short | 1 | 0 to 255 | td> | %uh
int (or) signed integer | 4 | -32768 to 32767 | %d or %i |
Unsigned integer | 4 | 0 to 65535 | % u |
Long (or) signed long | 4 | -2147483648 to 2147483647 | % d |
Unsigned long integer | 4 | 0 to 4294967295 | %lu |
Character data type | This data type is used to store characters. These characters are stored internally as integers. Each character has an equivalent ASCII value | For example: the ASCII value of 'A' is 65 |
Character data type
Range | |||
---|---|---|---|
th> | Char (or) Signature Char | 1 | - 128 to 127 |
Unsigned character | 1 | 0 to 255 | %c |
Floating point data type | is used to store real numbers (that is, decimal point numbers). | For 6 digits of precision, use "float". |
For 12-bit precision, use "double". >
For more than 12 digits of precision, use "long double".- Floating data type
Range | |||
---|---|---|---|
##Floating point | 4 | 3.4E - 38 to 3.4 E 38 | |
Double | 8 | 1.7 E - 308 to 1.7 E 308 | %lf |
Long double | 16 | 3.4 E - 4932 to 1.1 E 4932 | %Lf |
Example | The following are the supported | main data types - | Live demonstration |
The output is as follows-
DATA TYPE RANGE ----------- --------- short min -32768 short max int 32767 int min -2147483648 int max 2147483647 Char min -128 Char max 127 long min -2147483648 long max 2147483647 unsigned char 255 unsigned long 4294967295 unsigned int 4294967295 unsigned short 65535

C language data structure: The data representation of the tree and graph is a hierarchical data structure consisting of nodes. Each node contains a data element and a pointer to its child nodes. The binary tree is a special type of tree. Each node has at most two child nodes. The data represents structTreeNode{intdata;structTreeNode*left;structTreeNode*right;}; Operation creates a tree traversal tree (predecision, in-order, and later order) search tree insertion node deletes node graph is a collection of data structures, where elements are vertices, and they can be connected together through edges with right or unrighted data representing neighbors.

The truth about file operation problems: file opening failed: insufficient permissions, wrong paths, and file occupied. Data writing failed: the buffer is full, the file is not writable, and the disk space is insufficient. Other FAQs: slow file traversal, incorrect text file encoding, and binary file reading errors.

C language functions are the basis for code modularization and program building. They consist of declarations (function headers) and definitions (function bodies). C language uses values to pass parameters by default, but external variables can also be modified using address pass. Functions can have or have no return value, and the return value type must be consistent with the declaration. Function naming should be clear and easy to understand, using camel or underscore nomenclature. Follow the single responsibility principle and keep the function simplicity to improve maintainability and readability.

The calculation of C35 is essentially combinatorial mathematics, representing the number of combinations selected from 3 of 5 elements. The calculation formula is C53 = 5! / (3! * 2!), which can be directly calculated by loops to improve efficiency and avoid overflow. In addition, understanding the nature of combinations and mastering efficient calculation methods is crucial to solving many problems in the fields of probability statistics, cryptography, algorithm design, etc.

The C language function name definition includes: return value type, function name, parameter list and function body. Function names should be clear, concise and unified in style to avoid conflicts with keywords. Function names have scopes and can be used after declaration. Function pointers allow functions to be passed or assigned as arguments. Common errors include naming conflicts, mismatch of parameter types, and undeclared functions. Performance optimization focuses on function design and implementation, while clear and easy-to-read code is crucial.

C language functions are reusable code blocks. They receive input, perform operations, and return results, which modularly improves reusability and reduces complexity. The internal mechanism of the function includes parameter passing, function execution, and return values. The entire process involves optimization such as function inline. A good function is written following the principle of single responsibility, small number of parameters, naming specifications, and error handling. Pointers combined with functions can achieve more powerful functions, such as modifying external variable values. Function pointers pass functions as parameters or store addresses, and are used to implement dynamic calls to functions. Understanding function features and techniques is the key to writing efficient, maintainable, and easy to understand C programs.

C language multithreading programming guide: Creating threads: Use the pthread_create() function to specify thread ID, properties, and thread functions. Thread synchronization: Prevent data competition through mutexes, semaphores, and conditional variables. Practical case: Use multi-threading to calculate the Fibonacci number, assign tasks to multiple threads and synchronize the results. Troubleshooting: Solve problems such as program crashes, thread stop responses, and performance bottlenecks.

How to output a countdown in C? Answer: Use loop statements. Steps: 1. Define the variable n and store the countdown number to output; 2. Use the while loop to continuously print n until n is less than 1; 3. In the loop body, print out the value of n; 4. At the end of the loop, subtract n by 1 to output the next smaller reciprocal.
