ProblemLet’s write a C program to compute the row sum and column sum of a 5 x 5 array using run time compilation.SolutionIn this program, we are entering the values of array which is of size 5X5 matrix during runtime in the console, with the help of for loops we ... Read More

Array Of PointersJust like any other data type, we can also declare a pointer array.Declarationdatatype *pointername [size];For example, int *p[5]; //It represents an array of pointers that can hold 5 integer element addressesInitializationThe ‘&’ is used for initializationFor example,int a[3] = {10,20,30}; int *p[3], i; for (i=0; i

Pointers and arraysContinuous memory locations are allocated for all the elements of the array by the compiler.The base address is the location of the first element in the array.For example, int a [5] = {10, 20, 30, 40, 50};The five elements are stored as follows −If ‘p’ is declared as ...

If individual elements are to be passed as arguments, then array elements along with their subscripts must be given in function call.To receive the elements, simple variables are used in function definition.Example 1#include main (){    void display (int, int);    int a[5], i;    clrscr();    printf (“enter 5 ...

ArrayThe array is a group of related items that store with a common name. Following are the two ways of passing arrays as arguments to functions −sending entire array as argument to functionsending individual elements as argument to functionSending entire array as an argument to a functionTo send entire array ...
