C program to get input and print n elements in one dim array

In this article, we will discuss the concept of C program to get input and print n elements in one dim array

In this post, we are going to learn how to write a program to input and print n integer elements in single dimensional array in C language using for, while and do-while loop

Code to input and print integer in an array

Code to input and print integer in an array using for loop

In this code, we are going to learn how to input and print integer elements in single dimensional array using for loop in C language

Program 1

#include <stdio.h>
#define MAX_SIZE 1000 //define maximum size of the array

int main()
{
    int len,i;//Declare variables i and len
    int arr[MAX_SIZE];
    //int array declaration and initialization
     printf("Enter array length: ");
    scanf("%d",&len);

printf("Enter %d array elements!\n",len);
//take input from the user
    for(i=0; i<len; i++){
        printf("Input element for index arr[%d]: ",i);
        scanf("%d",&arr[i]);
        //input array elements using for loop
    }

    //display all elements in given array
    printf("\nElements of given array!\n");
    //display array elements
    for(i=0; i<5; i++){
         printf("Print element from index arr[%d]: ",i);
        printf("%d ", arr[i]);
        printf("\n");
        //display array elements using for loop
    }
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Code to input and print integer in an array using while loop

In this code, we are going to learn how to input and print integer elements in single dimensional array using while loop in C language

Program 1

#include <stdio.h>
#define MAX_SIZE 1000 //define maximum size of the array

int main()
{
    int len,i;//Declare variables i and len
    int arr[MAX_SIZE];
    //int array declaration and initialization
     printf("Enter array length: ");
    scanf("%d",&len);

printf("Enter %d array elements!\n",len);
//take input from the user
i=0;
    while(i<len){
        printf("Input element for index arr[%d]: ",i);
        scanf("%d",&arr[i]);
        //input array elements using while loop
         i++;
    }

    //display all elements in given array
    printf("\nElements of given array!\n");
    //display array elements
    i=0;
    while(i<len){
         printf("Print element from index arr[%d]: ",i);
        printf("%d ", arr[i]);
        printf("\n");
        //display array elements using while loop
         i++;
    }
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Code to input and print integer in an array using do-while loop

In this code, we are going to learn how to input and print integer elements in single dimensional array using do-while loop in C language

Program 1

#include <stdio.h>
#define MAX_SIZE 1000 //define maximum size of the array

int main()
{
    int len,i;//Declare variables i and len
    int arr[MAX_SIZE];
    //int array declaration and initialization
     printf("Enter array length: ");
    scanf("%d",&len);

printf("Enter %d array elements!\n",len);
//take input from the user
i=0;
    do{
        printf("Input element for index arr[%d]: ",i);
        scanf("%d",&arr[i]);
        //input array elements using do-while loop
         i++;
    }while(i<len);

    //display all elements in given array
    printf("\nElements of given array!\n");
    //display array elements
    i=0;
