In C language, storage classes specify how and where a variable is stored in memory. There are four storage classes in C: Here is an example of how to use storage classes in C: In this example, the function my_function contains three variables with different storage classes. The variable a has automatic storage, b has …
In C language, dynamic memory allocation allows you to allocate memory at runtime, rather than at compile time. This is useful when you don’t know the size of the memory that you need until the program is running. C provides several functions for dynamic memory allocation, including malloc, calloc, realloc, and free. These functions are …
A function can return an address, which is a memory location that contains a value. This can be useful in cases where you need to return a complex data type or a large data structure from a function. To return an address from a function in C, you need to define the function to return …
In C language, you can pass arrays as function arguments. When you pass an array to a function, the array is actually passed by reference, which means that the function receives a pointer to the first element of the array. This allows the function to access and modify the elements of the array. The syntax …
In C language, pointers and arrays are closely related concepts, and they can be used together in various ways. Pointer to Array: In C, you can create a pointer to an array, which is a variable that points to the first element of an array. The syntax for creating a pointer to an array is …
In C language, you can access array elements by using the array index notation, which is as follows: Here, array_name is the name of the array and index is the index of the element you want to access. Array indexing in C starts from zero, which means the first element of the array has an …
In C programming language, an array is a collection of elements of the same data type, stored in contiguous memory locations. Each element in the array is accessed using an index, which is an integer value that represents the position of the element in the array. Here is an example of declaring and initializing an …
