C++ Code to print array using while loop

C++ Code to print array using while loop

In this article, we will discuss the concept of C++ Code to print array using while loop

In this post, we are going to learn how to write a program to  print in an array using while loop in C++ language

Code to Display array elements

Program to print integers of an array using while loop – #1

In this code, we are going to learn how to display array of  integers using while loop in C++ language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int arr[6]={202,402,602,802,902,1102};
    //Array declaration and initialization
    cout << "Elements of given array" << endl;
    int i=0;
    while(i<6){
        cout<<arr[i]<<" ";
        i++;
    }
    getch();
    return 0;
}

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

Elements of given array
202, 402, 602, 802, 902,1102

 

Program to print integers of an array using while loop – #2

In this code, we are going to learn how to display array of  integers using while loop in C++ language

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int marks[5];
    marks[0]=31;
    marks[1]=13;
    marks[2]=63;
    marks[3]=71;
    marks[4]=78;
cout <<"Array elements are: ";
    int i=0;
    while( i<5){
        cout<< marks[i] << endl;
        i++;
    }
getch();
    return 0;
}

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

Array elements are: 31
13
63
71
78

 

 

Program to print strings of an array using while loop – #1

In this code, we are going to learn how to display array of  strings using while loop in C++ language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    string str[20];
    //Single one D array declaration
   str[0]="Donald";
   str[1]="Obama";
   str[2]="Rigan";
   str[3]="Lingan";
   str[4]="Michel";
//String array initialization
    cout<<"\nGiven students names are:\n";
    int i=0;
    while( i<5){
            cout<<"Index"<<" str=["<<i<<"]: ";
        cout<<str[i]<<"\n";
        //Display the students name using while loop
        i++;
    }
    getch();
    return 0;
}

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

Given students names are:

index str[0]: Donald;
index str[1]: Obama;
index str[2]: Rigan;
index str[3]: Lingan;
index str[4]: Michel;

 

Program to print strings of an array using while loop – #2

In this code, we are going to learn how to display array of  strings using while loop in C++ language

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    string str[20]{"Muththu","Appu","Kumaru","Alaku",};
    //Single one D array declaration
    //and initialization

  /* str[0]="Donald";
   str[1]="Obama";
   str[2]="Rigan";
   str[3]="Lingan";
   str[4]="Michel";
//String array initialization*/    cout<<"\nGiven students names are:\n";
    int i=0;
    while( i<4){
            cout<<"Index"<<" str=["<<i<<"]: ";
        cout<<str[i]<<"\n";
        //Display the students name using while loop
        i++;
    }
    getch();
    return 0;

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

Given students names are:

index str[0]: Muthu;
index str[1]: "Appu";
index str[2]: "Kumaru";
index str[3]: "Alaku";

 

Program to print characters of an array using while loop – #1

In this code, we are going to learn how to display array of  characters using while loop in C++ language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i;

    char char_array[4];
//Array declaration - char array

char_array[0]='c';
char_array[1]='h';
char_array[2]='a';
char_array[3]='r';
//Array initialization - char array

    cout<<"\ndisplay the characters\n";
    i=0;
      while(i<4){//display elements using while loop
      cout<<"char_array["<<i<<"]:"<<char_array[i];
      cout<<("\n");//Move to next line
       i++;
    }
getch();
    return 0;
}

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

Display the characters

char_array[0]=c;
char_array[1]=h;
char_array[2]=a;
char_array[3]=r;

Program to print characters of an array using while loop – #2

In this code, we are going to learn how to display array of  characters using while loop in C++ language

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i;

    char char_array[4]{'K','I','N','D'};
//Array declaration - char array

/*
char_array[0]='k';
char_array[1]='i';
char_array[2]='n';
char_array[3]='d';
//Array initialization - char array*/
    cout<<"\ndisplay the characters\n";
    i=0;
      while(i<4){//display elements using while loop
      cout<<"char_array["<<i<<"]:"<<char_array[i];
      cout<<("\n");//Move to next line
       i++;
    }
getch();
    return 0;
}

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

Display the characters

char_array[0]=K;
char_array[1]=I;
char_array[2]=N;
char_array[3]=D
