Break and Continue statements in C are looping control statements. Based on the break and continue statement loop can be broken or skipped break and continue both are keywords. break – Uses to break the loop and also use with a switch to break the switch case. continue– skip the current execution of the loop … Read more
Example: Write a program to assign the address of array elements to pointer variable and print the array element with address. #include int main () { int arr[] = {10, 20, 30}; int i, *ptr[3]; for ( i = 0; i < 3; i++) { ptr[i] = &arr[i]; // assign the address array element to ... Read more
In a C programming language a function is a group of statements that together perform a special task. In every C program has at least one function, which is main(). In a C library has a numerous predefined or built-in functions. For example, strcat() to concatenate two strings, main() from where program execution starts. In a C programming … Read more
Example: Write a program to multiply two matrix. Firstly, ask from user order of matrix( number of rows and column) Then take the elements of matrix from user as a input and print the resultant matrix. #include int main() { int m, n, p, q, i, j, k, sum = 0; int f[10][10], s[10][10], multiply[10][10]; … Read more
A pointer that is assigned NULL is called a null pointer. We must initialize NULL pointer during variable declaration. A null pointer refers to pointer variable that does not point to a valid address. Generally NULL pointer is used when you do not have an exact address to be assigned. #include int main () { int *ptr … Read more
Call by value and Call by reference in C are two ways to pass arguments in a function Lets see above one by one Call by value Whenever we call a function and passes the value of variable to the called function is called call by value. #include void swap(int x, int y); /* function … Read more
C programming language also support multidimensional arrays. Syntax of multidimensional array declaration: Data_type array_name[size1][size2]…[sizeN]; For example, if we want to creates a three dimensional integer array − int num[5][10][4]; Two-dimensional Arrays The simplest form of multidimensional array is the two-dimensional array. if we want to declare a two dimensional integer array of size [x][y] ( … Read more
In C language, a pointer is an address. Normally, a pointer variable contains the address of a another variable. A pointer to a pointer is a chain of pointers. Or Pointer to pointer means one pointer variable holds the address of another pointer variable. #include int main() { int a=4; int *b, **c; b = … Read more
In programming, variable is used to hole the value & this variable stored in a memory. Each variable has a address to identify where these variables actually stored in a memory. In a C programming language, pointer is a variable which can hold the address of another variable. Accessing Address of Variable In … Read more
In C programming language, a function that calls itself is known as a recursive function. And, this technique is called as recursion. Recursive functions are very useful to solve many problems such as Towers of Hanoi (TOH), Inorder/Preorder/Postorder Tree Traversals, DFS of Graph, etc. How recursion works? void recurse() { … .. … recurse(); … .. … … Read more
