C++ program to read and display characters of an array

In this tutorial, we will discuss the concept of C++ program to read and display characters of an array

In this topic, we are going to learn how to read and print characters using one dimensional array in C++ programming language using loops.

In this blog, We have already discuss that “What is an array“, type of arrays and how to access it(one dim, two dim and three dim arrays)

Arrays are the special type of variables to store Multiple type of values(int, string,char, etc)under the same name in the continuous memory location. we can be easily accessed using the indices(indexes)

C++ program to read and display characters in an array — Program to read and display characters

Here,

C,H,A and R represent the characters elements of the array
0,1,2,3 and 4 represent the index of the array which is used to access the array elements
1,2,3,4 and 5 represent the length of the array

Code to read and print characters of one dim array

Read and print characters Using for loop

In this program, we are briefing input characters of an array and then print them using for loop in C++ language

Program 1

#include 
#include 
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
    char char_array[len];
//Array declaration
      cout<<"\n";//move to next line

       cout<<"Enter the characters for array :";
       //Ask input for elements(numbers)
    for(i=0; i>char_array[i];
      //Reading the array elements from user
    }
    cout<<"\ndisplay the characters\n";
      for(i=0; i
When the above code is executed, it produces the following result
Enter the array length: 7
Enter the characters for array: Program
Display the characters

Program 2
#include 
#include 
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
    char char_array[len];
//Array declaration
      cout<<"\n";//move to next line

      cout<<"Enter the characters for array :\n";
       //Ask input for elements(numbers)
    for(i=0; i>char_array[i];
      //Reading the array elements from user
    }
    cout<<"\ndisplay the characters\n";
      for(i=0; i
When the above code is executed, it produces the following result
Output
 
Read and display characters  using while loop
In this program, we are briefing input characters of an array and then print them using while loop in C++ language
Program 1
#include 
#include 
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
    char char_array[len];
//character Array declaration
      cout<<"\n";//move to next line

       cout<<"Enter the characters for array :";
       //Ask input for elements(numbers)
       i=0;
    while(i>char_array[i];
      //Reading the array elements from user
       i++;
    }
    cout<<"\ndisplay the characters\n";
    i=0;
      while(i
When the above code is executed, it produces the following result
Enter the array length: 11
Enter the characters for array: Code4coding
Display the characters

#include 
#include 
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
    char char_array[len];
//Array declaration
      cout<<"\n";//move to next line

      cout<<"Enter the characters for array :\n";
       //Ask input for elements(numbers)
       i=0;
    while(i>char_array[i];
      //Reading the array elements from user
       i++;
    }
    cout<<"\ndisplay the characters\n";
    i=0;
      while(i
When the above code is executed, it produces the following result

Read and display characters using do- while loop
In this program, we are briefing input characters of an array and then print them using do-while loop in C++ language
Program 1
#include 
#include 
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
    char char_array[len];
//character Array declaration
      cout<<"\n";//move to next line

       cout<<"Enter the characters for array :";
       //Ask input for elements(numbers)
       i=0;
    do{//input using for loop
      cin>>char_array[i];
      //Reading the array elements from user
       i++;
    }while(i
When the above code is executed, it produces the following result
Enter the array length: 9
Enter the characters for array: Clanguage
Display the characters

      cout<<"\n";//move to next line

      cout<<"Enter the characters for array :\n";
       //Ask input for elements(numbers)
       i=0;
    do{//input using for loop
    cout<<"char_array["<>char_array[i];
      //Reading the array elements from user
       i++;
    }while(i
When the above code is executed, it produces the following result
