C Programming (Page 2)

Command Line Arguments in C Language: It is a procedure of passing the arguments to the main function from the command prompt. By using command-line arguments, we can create user-defined commands. In the implementation, when we were required to develop an application for the DOS operating system then recommended goingContinue Reading

Void Pointer in C: The Generic pointer of C & C++ is called a void pointer. A generic pointer means it can access and manipulate the data of any kind of variable. The Size of the void pointer is 2 bytes. By using a void pointer, when we are accessingContinue Reading

What is a Null Pointer? A Null Pointer in C Programming Language is a pointer that does not point to any memory location i.e. it does not hold the address of any variables. It only stores the base address of the segment. That means the null pointer in C storesContinue Reading

What is Const in C? The keyword const in C Programming Language can be applied to the declaration of any variable to specify that its value will not be changed. The most important point that you need to remember is the keyword const applies to whatever is there immediately toContinue Reading

Character Pointer in C Language: A pointer may be a special memory location that’s capable of holding the address of another memory cell. So a personality pointer may be a pointer that will point to any location holding character only. Character array is employed to store characters in Contiguous MemoryContinue Reading

Pointer to Function in C Language Pointers can also be passed as an argument to a function like any other argument. Instead of a variable, when we pass a pointer as an argument then the address of that variable is passed instead of the value. So any change made toContinue Reading

Pointer to Array of functions in C #include <stdio.h> #define SIZE 10 int main() { int arr[SIZE]; int *ptr = arr; int i; printf(“Enter %d array elements: “,SIZE); while(ptr < &arr[SIZE]) { scanf(“%d”, ptr); ptr++; } ptr = arr; printf(“Elements in array are: “); for(i=0; i < SIZE; i++) {Continue Reading

Pointer to Pointer (Double Pointer) in C Language: It is a concept of holding the pointer address into another pointer variable. In C Language, a pointer variable points to a location in memory and is used to store the address of a variable. In C, we can also define aContinue Reading

Arithmetic Operations on Pointers in C: As we already discussed in our previous article, the Pointers variables are used to store the address of another variable. The address is nothing but the memory location assigned to the variable. That means the pointer doesn’t store any value, it stores the address.Continue Reading
