Print given sentence into its equivalent ASCII form

Last Updated : 06 May, 2021

Given a string containing words forming a sentence(belonging to english language). The task is to output the equivalent ASCII sentence of the input sentence.
ASCII form of a sentence is the conversion of each of the character of the input string and aligning them in position of characters present in the string
Examples:

Input : hello, world!
Output : ASCII Sentence:
         104101108108111443211911111410810033

Input : GeeksforGeeks
Output : ASCII Sentence:
         7110110110711510211111471101101107115

Explanation:
To complete the task, we need to convert each character into it’s equivalent ASCII value. We perform the following steps to achieve the equivalent ASCII form of the given sentence-

Iterate over the length of the complete sentence/string
Take each character of the sentence at a time, subtract NULL character to it and explicitly typecast the result
Print the result

Following the above steps, we can achieve the equivalent ASCII form of a given sentence/string.

C++

// C++ implementation for converting
// a string into it's ASCII equivalent sentence
#include <bits/stdc++.h>
using namespace std;
 
// Function to compute the ASCII value of each
// character one by one
void ASCIISentence(std::string str)
{
    int l = str.length();
    int convert;
    for (int i = 0; i < l; i++) {
        convert = str[i] - NULL;
        cout << convert;
    }
}
 
// Driver function
int main()
{
    string str = "GeeksforGeeks";
    cout << "ASCII Sentence:" << std::endl;
    ASCIISentence(str);
    return 0;
}

class GeeksforGeeks {
 
    // Function to compute the ASCII value of each
    // character one by one
    static void ASCIISentence(String str)
    {
        int l = str.length();
        int convert;
        for (int i = 0; i < l; i++) {
            convert = str.charAt(i);
            System.out.print(convert);
        }
    }
 
    // Driver function
    public static void main(String args[])

        System.out.println("ASCII Sentence:");
        ASCIISentence(str);
    }
}

<?php
// PHP implementation for converting a
// string into it's ASCII equivalent sentence
 
// Function to compute the ASCII
// value of each character one by one
function ASCIISentence($str)
{
    for ($i = 0; $i< strlen($str); $i++)
        echo ord($str[$i]);
}
     
// Driver code
$str = "GeeksforGeeks";

Javascript

<script>
// Javascript implementation for converting
// a string into it's ASCII equivalent sentence   
     
    // Function to compute the ASCII value of each
    // character one by one
    function ASCIISentence(str)
    {
        let l = str.length;
        let convert;
        for (let i = 0; i < l; i++) {
            convert = str[i].charCodeAt(0);
            document.write(convert);
        }
    }
     
    // Driver function
    let str = "GeeksforGeeks";
    document.write("ASCII Sentence:<br>");
    ASCIISentence(str);
     
    // This code is contributed by rag2127
</script>

Output:

ASCII Sentence:
7110110110711510211111471101101107115

The time-complexity of converting into equivalent ASCII sentence is $O(len)$ , where len is the length of the string.
Application:

Sentence in english language could be encoded/decoded into this form e.g. convert a sentence into it’s equivalent ASCII form and add 5 to each digit and send it from encoder’s side. Later, decoder can subtract 5 from each digit and decode it into it’s original form. This way only the sender and the receiver would be able to decode the sentence.
ASCII form is also used to transfer data from one computer to another.
