how to to unlock android mobile without reset

 There are a few ways to unlock an Android mobile device without resetting it:

1. Use the Google account associated with the device: If you have forgotten your screen lock, you can try unlocking the device using the Google account that is associated with it. Enter your email address and password when prompted, and if they are correct, the device will be unlocked.

2. Use the "Forgot pattern" or "Forgot PIN" feature: If you have a pattern or PIN screen lock, some devices have a "Forgot pattern" or "Forgot PIN" feature that allows you to reset the lock using your Google account.

3. Use Android Device Manager: Android Device Manager is a service provided by Google that allows you to remotely locate, lock, or erase your device. If your device is lost or stolen, you can use this service to remotely unlock your device.

4. Use a third-party software: There are third-party software that claims to be able to unlock Android devices without resetting them, however, it's important to use a reputable software, as some of the software may damage your device or put your personal data at risk.

It's important to note that if none of these methods work, and you don't have a backup of your device, you may need to reset it. This will erase all data on the device and restore it to its factory settings.

Printf statement in C Language

 The printf() function is a standard C library function that is used to output text to the console. It is included in the stdio.h header file and is used to print characters, strings, and other data types to the screen.

The basic syntax for using the printf() function is:

bash
printf("format string", argument1, argument2, ...);

The "format string" is a string that contains text and special placeholders called format specifiers, which are used to insert the values of the arguments into the string.

Here are some examples of how to use the printf() function:

• Print a string:

bash
printf("Hello, World!");

• Print an integer:

perl
int age = 25;
printf("I am %d years old.", age);

• Print a floating-point number:

bash
float pi = 3.14159;
printf("The value of pi is approximately %f.", pi);

• Print multiple values:

perl
int x = 5, y = 10;
printf("The value of x is %d and the value of y is %d.", x, y);

The printf() function also allows you to specify the width, precision, and alignment of the output using format specifiers. For example, you can control the number of decimal places printed for a floating-point number or specify the minimum width of a field.

It's worth noting that the printf() function returns the number of characters that were printed. This can be useful for checking if the function was successful or for counting the number of characters in the output.

C language introduce

 A c program is a computer program written in the C programming language. The C programming language is a high-level, procedural programming language that was first developed in the 1970s by Dennis Ritchie at Bell Labs. C is a widely used language and is known for its efficiency and ability to handle low-level operations.

A simple C program may look something like this:

c
#include <stdio.h>

int main() {
    printf("Hello, World!");
    return 0;
}

This program will output "Hello, World!" to the console when run.

The first line #include <stdio.h> is a preprocessor directive that tells the compiler to include the contents of the standard input/output header file (stdio.h) in the program. The stdio.h header file contains functions such as printf() and scanf() that are used for input and output operations.

The next line int main() declares the main function of the program. The main function is the starting point of the program and is required for a C program to run.

The next line printf("Hello, World!"); uses the printf() function to output the string "Hello, World!" to the console.

The last line return 0; indicates that the main function has completed successfully and returns a value of 0 to the operating system.

It's worth noting that this is a very basic example and C programs can be much more complex, with multiple functions, variables, control structures, and more.

Advanced HTML tags

 There are several advanced HTML tags that are not as commonly used as the basic tags, but can be very useful in certain situations. Some examples include:

1. <figure> and <figcaption>: These tags are used to create a figure with a caption. The figure element can contain images, videos, or other multimedia, and the figcaption element can be used to provide a caption for the figure.

2. <time>: This tag is used to indicate a specific date or time in the HTML document. It can be used in conjunction with the datetime attribute to specify the date and time in machine-readable format.

3. <mark>: The <mark> tag is used to highlight text, making it stand out on the page. It is often used to indicate search keywords or other important information.

4. <details> and <summary> : These tags are used to create a widget that the user can open and close. The <summary> tag defines a visible summary or legend for the details that the user can see, and the <details> tag contains the additional information that the user can reveal or hide.

5. <figure> : Is a tag that is used to group multimedia content like image and video.

6. <canvas> : Is a tag that is used to draw graphics, on the fly, via scripting (usually JavaScript).

7. <audio> and <video> : These tags are used to embed audio and video in HTML5.

8. <source> : This tag is used along with <audio> and <video> to specify the sources for the audio and video files.

9. <progress> : This tag is used to indicate the completion progress of a task.

10. <template> : This tag is used to create a container for HTML that is not rendered when the page is loaded, but can be activated later by JavaScript.

It's worth noting that many of these tags are only supported in the latest versions of web browsers, so it's important to check for browser compatibility before using them in your projects.
