Read More_Generic keyword in C ? 1: 20
The _Generic keyword in C is used to define type-generic macros that can work with different data types. This keyword was introduced in the C11 standard to enable compile-time type selection, allowing a single macro to behave differently based on the type of its argument. Syntax #define macro_name(x) _Generic((x), \ type1: expression1, \ type2: expression2, \ default: default_expression \ )(x) The _Generic expression evaluates to one of the specified expressions based on the type of the controlling expression (x).

Read MoreA Product Array Puzzle in C?
A Product Array Puzzle is a common programming problem where we need to construct an array such that each element contains the product of all elements in the original array except the element at that position. The constraint is that we cannot use the division operator. Syntax void productArray(int arr[], int n, int result[]); // arr[] - input array // n - size of array // result[] - output array containing products Approach: Using Left and Right Product Arrays The solution uses two auxiliary arrays to store products of elements to the ...

Read MoreDeep Copy of Struct Member Arrays in C
In C, when you assign one structure variable to another, a shallow copy is typically performed. However, there is an important exception: if a structure member is an array, the compiler automatically performs a deep copy of that array. This means the array contents are copied element by element, creating independent copies in memory. Syntax struct_type destination = source; // Assignment copies all members Example: Deep Copy of Array Members The following example demonstrates how array members within structures are deep copied automatically − #include #include typedef struct ...
Read MoreC Program for Armstrong Numbers
An Armstrong number (also known as narcissistic number) is a number that is equal to the sum of its own digits raised to the power of the number of digits. For example, 153 is an Armstrong number because 1³ + 5³ + 3³ = 1 + 125 + 27 = 153. Syntax int armstrong(int number); Formula For an n-digit number with digits d₁, d₂, ..., dₙ − Armstrong Number = d₁ⁿ + d₂ⁿ + ... + dₙⁿ Example: 153 (3-digit number) 1³ + 5³ + ...
