Union in c Union is a user defined data type member in C programming. Which specifically stores different data types program variables elements in the same memory storage location. In union C structure where each structure member has its own individual memory storage location. All variable members of the same union data type use the…
Structure pointers Using pointer operators for structure data type members allows you to efficiently manipulate structure data type members within the declared structure and to access structure members from memory address locations, especially when dynamic memory allocation is needed for a structure or passing a function to a structure. So let's use structure to pointer…
Nested structures in c Nested Structure In C programming, when we declare another sub-structure in a structure. Those which are declared as another structure member inside a structure. They are called nested structure data type. Whenever you define new other types of structure members as data type inside another structure. Nested structures help you to…
Accessing structure members If you want to access the structure members individually in the C program, then you can use the dot (.) operator in the structure to work directly with the declared structure variable. Similarly, when you use pointers in the structure, you call the structure members using the arrow (->) operator. So let's…
Structure Declaration and definition Use of Structure Data Type (Structure) Members In C Programming, different types of program data type variables are grouped together and processed under a single structure member name. Structures in C language provide you the features to create and process complex data type programs. Remember that any C program structure can…
Character arrays vs. string literals Character arrays and string literals are used in C programming to fulfill different programming tasks, and they have different string array properties. Especially they are used to solve some specific string operations. Character array declaration in C. Character array declaration and initialization. char text[50]; // 50 Character array declaration named…
String manipulation functions (strcpy, strcat, strlen, etc.) String Manipulation Built-in string functions are used in C programming language to perform various types of string operations on string text or paragraphs. You can apply many string operations in C program by declaring character string as array such as copying a string, joining two different strings, comparing…
Declaration and initialization Strings data type is usually used in C programming language to store character string array text or small paragraph information. Because C language stores and displays 1 byte single character in character data type by default. It is more convenient and easy to declare and process string as array in C program.…
Dynamic memory allocation (malloc, calloc, realloc, free) Dynamic memory allocation in C programming allows the program to allocate new memory, reallocate existing memory, and free memory space allocated by the malloc function when memory is requested at runtime. This makes it more flexible and easy to manage different types of program variable data and to…
Pointer to functions A pointer to function in C program is a type of pointer memory address location variable. Which stores the memory address of the function argument/parameter instead of a program variable declared in the C program. Pointer to function is especially useful in programming conditions where you want to pass an argument or…
