How do you declare an int array?

Answer 1

we define the array is

Array array[]={1,2,3,4,5} this is the integer Array

Array array[]={"apple","banana","carrot","mango"} this is the String Array

Answer 2

A simple formula to declare arrays in C++ is as:

1. For 1D or one dimensional array:

data_type name_of_array[size_of_array] ;

For example, if I want to declare a 1D array named marks, of integer type with a size 10, I will write

int marks [10];

2. For 2D or two dimensional arrays:

data_type name_of_array[number_of_rows][number_of_columns] ;

For example, to declare any floating point, 2D array, with 3 rows and 5 columns, I will write

float sample [3][5];

Answer 3

//array understanding program

import java.io.*;

class arraydemo1

{

public static void main(String args[])throws IOException

{

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

System.out.println("Number of subjects are:");

int n=Integer.parseInt(br.readLine());

int marks[]=new int[n];

for(int i=0; i<n;i++)

{

System.out.println("enter marks:");

marks[i]=Integer.parseInt(br.readLine());

}

int total=0;

for(int i=0; i<n;i++)

{

total=total+marks[i];

}

System.out.println("total marks are:"+total);

}

}

Answer 4

My answer is specific for C/C++ programming languages.

• For declaration of integer array in C/C++
  

Example:
int arrayName[n];
// where n is the number of elements

• For initialization of integer array in C/C++
  

Example:
int oddNumbers[5] = {1, 3, 5, 7, 9};

Answer 5

Here's are examples:

int[] array;

int array[];

int[] array = {1, 2, 3};

Answer 6

This is done somewhat differently in different programming languages, due to syntax differences.

Basically you declare an array whose elements are integers.

Answer 7

Example: char *argv[]
