Print given sentence into its equivalent ASCII form

Given a string containing words forming a sentence (belonging to the English language). The task is to output the equivalent ASCII sentence of the input sentence. 
ASCII (American Standard Code for Information Interchange) form of a sentence is the conversion of each of the characters of the input string and aligning them in the 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 its 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.

{
    int l = str.length();
    int convert;
    for (int i = 0; i < l; i++) {
        convert = str[i];
        cout << convert;
    }
}

// Driver function

{
    string str = "GeeksforGeeks";
    cout << "ASCII Sentence:" << std::endl;
    ASCIISentence(str);
    return 0;

ASCII Sentence:
7110110110711510211111471101101107115

Time Complexity: O(N), as we are using a loop to traverse N times. Where N is the length of the string.
Auxiliary Space: O(N), as we are using extra space for convert 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.
