Dynamic Memory Allocation in C

by

Dynamic memory allocation in C allows you to allocate memory at runtime, rather than at compile-time. This means that you can request memory as your program runs, rather than having to pre-allocate a fixed amount of memory at the start of your program. In C, dynamic memory allocation is typically performed using the functions `malloc()`, … Read more

Typedef in C

by

In C programming language, typedef is a keyword that enables the programmer to create aliases (or alternate names) for existing data types. Typedef enables the programmer to create more readable code by giving meaningful names to data types. To use typedef in C, you need to define a new name for an existing data type. … Read more

Enumerations in C

by

In C programming language, an enumeration (or enum for short) is a user-defined data type that consists of a set of named integer constants. Enumerations enable the programmer to create a set of named values that can be used in a program. To declare an enumeration in C, you need to define its named constants. … Read more

Unions in C

by

In C programming language, a union is a user-defined data type that allows multiple variables of different data types to share the same memory space. Unions enable the programmer to create a single variable that can be interpreted as different data types. To declare a union in C, you need to define its members and … Read more

Structures in C

by

In C programming language, a structure is a user-defined data type that groups together variables of different data types under a single name. Structures enable the programmer to create complex data structures that can be easily manipulated in a program. To declare a structure in C, you need to define its members and their data … Read more

String Functions in C

by

C programming language provides several built-in functions in the standard library to manipulate strings. Here are some of the most commonly used string functions in C: 1. strlen(): This function returns the length of a string (not including the null character ‘\0’). #include #include int main() { char str[] = “Hello, world!”; int len = … Read more

Strings in C

by

In C programming language, a string is a sequence of characters that is terminated by a null character ‘\0’. Strings are commonly used to represent text in programs. To declare a string in C, you can use an array of characters. Here’s an example of how to declare and initialize a string in C: char … Read more

Multidimensional Arrays in C

by

In C programming language, a multidimensional array is an array that contains one or more arrays as its elements. Multidimensional arrays are useful for storing and accessing data that has multiple dimensions, such as matrices and tables. To declare a multidimensional array in C, you need to specify the data type of the elements and … Read more

Arrays in C

by

In C programming language, an array is a collection of elements of the same data type that are stored in contiguous memory locations. Arrays are useful for storing and accessing large amounts of data efficiently. To declare an array in C, you need to specify the data type of the elements and the number of … Read more

Arrays and Pointers in C

by

In C programming language, arrays and pointers are closely related. In fact, an array can be thought of as a pointer to the first element of the array. When an array is declared, the name of the array is actually a pointer to the first element of the array. Here’s an example of how to … Read more
