Accept array input and print
Table of Contents
In this article, we will discuss the concept of C++ program to accept array input and print using Do-While loop
In this post, we are going to learn how to write a program to read array input and print given elements in an array using do-while loop in C++ language
In this code, we are going to learn how to read integer array input given by user and print the them using do-while loop in C++ language
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,len;//integer variable declaration
cout<<"Enter the Array length: ";
//Ask input for array length
cin>>len;
//Reading the input for array length
int num[len];
//Array declaration - one dimension
cout<<"\n";//move to next line
cout<<"Enter the Number for array :";
//Ask input for elements(marks)
i=0;
do{//takes input using for loop
cin>>num[i];
//Reading the array elements from user
i++;
}while(i<len);
cout<<"\ndisplay the number\n";
i=0;
do{//display elements using do-while loop
cout<<num[i];
cout<<("\n");
i++;
}while(i<len);
getch();
return 0;
}
When the above code is executed, it produces the following result
Program 2
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,len;//Variable declaration-integer
cout<<"Enter the Array length: ";
//Ask input for array length
cin>>len;
//Reading the input for array length
int num[len];
//Array declaration
cout<<"\n";//move to next line
i=0;
//Ask input for elements(number)
do{//input using do-while loop
cout<<"Enter the numbers "<<"num["<<i<<"] :";
cin>>num[i];
//Reading the array elements from user
i++;
}while( i<len);
cout<<"\ndisplay the numbers\n";
i=0;
do{//display elements using do-while loop
cout<<"num["<<i<<"] :"<<num[i];
cout<<("\n");
i++;
}while(i<len);
getch();
return 0;
}
When the above code is executed, it produces the following result
Enter the array length: 4 Enter the numbers num[0]: 6357 Enter the numbers num[1]: 8347 Enter the numbers num[2]: 9123 Enter the numbers num[3]: 4556 Display the numbers num[0]=6357 num[1]: 8347 num[2]: 9123 num[3]: 4556
In this code, we are going to learn how to read string array input given by user and print the them using do-while loop in C++ language
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
int len;
cout<<"Enter array length\n";
cin>>len;
cout<<"\nEnter students name\n";
int i=0;
do{
cin>>str[i];
i++;
}while(i<len);
cout<<"\nEntered students names are:\n";
int j=0;
do{
cout<<str[j]<<"\n";
j++;
}while(j<len);
getch();
return 0;
}
When the above code is executed, it produces the following result
Program 2
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
int len;
cout<<"Enter array length\n";
cin>>len;
cout<<"\nEnter students name\n";
int i=0;
do{
cout<<"Enter the string"<<" str=["<<i<<"]: ";
cin>>str[i];
i++;
}while(i<len);
cout<<"\nEntered students names are:\n";
int j=0;
do{
cout<<"Your entered string is:"<<" str=["<<j<<"]: ";
cout<<str[j]<<"\n";
j++;
}while(j<len);
getch();
return 0;
}
When the above code is executed, it produces the following result
In this code, we are going to learn how to read character array input given by user and print the them using do-while loop in C++ language
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,len;
//variable declaration for integer
cout<<"Enter the Array length: ";
//Request input for array length
cin>>len;
//Reading the input for array length
char char_array[len];
//character Array declaration
cout<<"\n";//move to next line
cout<<"Enter the characters for array :";
//Request input for elements(numbers)
i=0;
do{//input using for loop
cin>>char_array[i];
//Reading the array elements from user
i++;
}while(i<len);
cout<<"\ndisplay the characters\n";
i=0;
do{//display elements using for loop
cout<<char_array[i];
cout<<("\n");
i++;
} while(i<len);
getch();
return 0;
}
When the above code is executed, it produces the following result
Program 2
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,len;
//variable declaration for integer
cout<<"Enter the Array length: ";
//Request input for array length
cin>>len;
//Reading the input for array length
char char_array[len];
//Array declaration
cout<<"\n";//move to next line
cout<<"Enter the characters for array :\n";
//Request input for elements(numbers)
i=0;
do{//input using for loop
cout<<"char_array["<<i<<"]:";
cin>>char_array[i];
//Reading the array elements from user
i++;
}while(i<len);
cout<<"\ndisplay the characters\n";
i=0;
do{//display elements using for loop
cout<<"char_array["<<i<<"]:"<<char_array[i];
cout<<("\n");
i++;
}while(i<len);
getch();
return 0;
}
When the above code is executed, it produces the following result
