What are the scope rules to functions in C programming?
Scope rules in C programming define where variables and functions can be accessed within a program. These rules determine the visibility and lifetime of variables based on where they are declared. Syntax /* Global scope */ data_type variable_name; function_name() { /* Local scope */ data_type variable_name; } Local Scope Local scope specifies that variables defined within a block are visible only in that block and invisible outside the block. These variables exist only during the function execution. Global Scope Global scope specifies that ...
Read MoreChange CSS filter property with Animation
The CSS filter property can be animated to create smooth visual effects on elements. By combining filter with CSS animations, you can create dynamic transitions between different filter states like brightness, contrast, blur, and more. Syntax selector { filter: filter-function(value); animation: animation-name duration timing-function iteration-count; } @keyframes animation-name { from { filter: initial-value; } to { filter: final-value; } } Example: Animated Contrast Filter The following example demonstrates animating the contrast filter on an image − ...
Read MoreSoft Credit Inquiry
A soft credit inquiry is a type of credit check that allows lenders, employers, or individuals to view your credit report without impacting your credit score. Unlike hard inquiries, soft inquiries do not require your explicit permission and are typically used for background checks or pre-qualification purposes. Key Concepts A soft credit inquiry, also called a soft pull, is essentially a background check on your creditworthiness. When you check your own credit score, this is classified as a soft inquiry. These inquiries may be performed by employers conducting background checks, banks evaluating your eligibility for credit cards, or ...
Read MoreWhat are the different types of functions in C Programming?
Functions in C programming are broadly classified into two types which are as follows − Predefined functions User-defined functions Predefined (or) Library Functions Predefined functions are already defined in the system libraries. These functions allow programmers to reuse existing code, which helps write error-free programs efficiently. The user must be aware of the syntax and header file required for each function. These functions are pre-written and tested by system developers They are available in standard library header files like stdio.h, math.h, string.h Programmer needs to include the appropriate header file to use them ...
Read MoreChange CSS columns property with Animation
The CSS columns property can be animated to create dynamic multi-column layouts. This property is a shorthand for column-width and column-count, allowing you to animate column changes smoothly. Syntax selector { columns: column-width column-count; animation: animation-name duration timing-function; } Example: Animating Column Properties The following example demonstrates how to animate the columns property along with related column styling − .container { width: 600px; ...
Read MoreHow to write a C program to find the roots of a quadratic equation?
A quadratic equation is of the form ax² + bx + c = 0, where a, b, and c are coefficients and a ≠ 0. The roots can be found using the quadratic formula, and the nature of roots depends on the discriminant value. Syntax r1 = (-b + sqrt(discriminant)) / (2 * a); r2 = (-b - sqrt(discriminant)) / (2 * a); Mathematical Formula The quadratic formula is − r₁ = (-b + √(b² - 4ac)) / (2a) r₂ = (-b - √(b² - 4ac)) / (2a) Where the discriminant (d) ...
Read MoreUsage of rgba() CSS function
The rgba() CSS function is used to define colors using the Red, Green, Blue, and Alpha (transparency) model. It extends the basic rgb() function by adding an alpha channel that controls the opacity of the color. Syntax selector { property: rgba(red, green, blue, alpha); } Possible Values ParameterValue RangeDescription red0-255Red component of the color green0-255Green component of the color blue0-255Blue component of the color alpha0-1Opacity level (0 = transparent, 1 = opaque) Example: Using rgba() with Different Alpha Values The following example demonstrates rgba() colors with ...
Read MoreShort Interest
Short interest refers to the total number of shares of a particular stock that have been sold short but have not yet been covered or closed out. This metric serves as an important indicator of market sentiment, as it reveals how many investors are betting against a stock's price performance. Formula Short interest can be calculated and expressed in two ways: $$\mathrm{Short\ Interest\ Ratio = \frac{Number\ of\ Shares\ Sold\ Short}{Average\ Daily\ Trading\ Volume}}$$ $$\mathrm{Short\ Interest\ Percentage = \frac{Number\ of\ Shares\ Sold\ Short}{Total\ Outstanding\ Shares} \times 100}$$ Number of Shares Sold Short ...
Read MoreUsage of CSS grid-auto-columns property
The CSS grid-auto-columns property sets the default size for columns that are created implicitly in a grid container. This property is useful when grid items are placed outside the explicitly defined grid tracks. Syntax .container { grid-auto-columns: value; } Possible Values ValueDescription lengthFixed size using px, em, rem, etc. %Percentage of the container width frFractional unit for flexible sizing autoSize based on content (default) min-contentMinimum size needed for content max-contentMaximum size needed for content Example: Fixed Column Size The following example demonstrates grid-auto-columns with a fixed ...
Read MoreConvert vowels from upper to lower or lower to upper using C program
In C programming, we can convert vowels in a string from uppercase to lowercase or lowercase to uppercase using character manipulation functions. This involves checking each character to identify vowels and then applying the appropriate case conversion. Syntax #include int toupper(int c); // Converts to uppercase int tolower(int c); // Converts to lowercase Method 1: Convert Lowercase Vowels to Uppercase This approach converts all lowercase vowels (a, e, i, o, u) to their uppercase equivalents while keeping other characters unchanged − #include #include ...
