Method 2: Initialize an array in C using a for loop We can also use theforloop to set the elements of an array. #include<stdio.h>intmain(){// Declare the arrayintarr[5];for(inti=0;i<5;i++)arr[i]=i;for(inti=0;i<5;i++)printf("%d\n",arr[i]);return0;} Copy Output 0...
printf("Array of characters: %sn", myArray); return 0; } In this example, we declare and initialize an array of characters named myArray. The array is initialized with the characters ‘H’, ‘e’, ‘l’, ‘l’, ‘o’, and ‘�’ (the null character). The null character is us...

In this tutorial, you will learn to work with arrays. You will learn to declare, initialize and access array elements of an array with the help of examples. An array is a variable that can store multiple values.
The complete program to declare an array of the struct in C is as follows. #include <stdio.h> // Define the structure struct Student { int rollNumber; char studentName[20]; float percentage; }; int main() { // Declare and initialize an array of structs struct Student studentRecord[5...
You can declare an array as follows: data_type array_name[array_size]; e.g. int a[5]; where int is data type of array a which can store 5 variables. Initialization of Array in C You can initialize array by using index. Always array index starts from 0 and ends with [array_size ...
In this example, we declare an array of threeStudentstructs and initialize it with three different students. Each student’s data is provided in a structured format, making it easy to read and understand. Theforloop then iterates through the array, printing the details of each student. This ...

This post will discuss how to declare and initialize arrays in C/C++. 1. Declare Arrays in C/C++ ⮚ Allocate memory on Stack In C/C++, we can create an array, as shown below: 1 intarr[5]; The above code creates a static integer array having size 5. It will allocate the memory...
