Question

Q20. Using C++ style string to write a program that reads a sentence as input and converts each word of the sentence following the rule below:

• For every word in the sentence, the first letter is relocated the end of the word.
• Then append the string “KPU” to the word.

More requirements:

• All letters in the output should be uppercase.

More assumptions:

• The input sentence contains no non-alphabetic letters

Sample Run:

Please enter the original sentence: i LOVE to program
Translated: IKPU OVELKPU OTKPU ROGRAMPKPU

Answer 1

Implement the program as follows:

1. declare string variables
2. ask the user to enter a sentence
3. read complete sentence to sentence
4. for each character in sentence, do the following,
5. if character = ' ', it denotes the end of a word
6. relocate first character to end, append "KPU" and append it to translated string
7. set word = ""
8. otherwise convert character to upper-case, cast to character and append it to word
9. for the last word, relocate first character to end, append "KPU" and append it to translated string
10. print translated string

Program:

#include <iostream>

using namespace std;

int main()
{
    string sentence, word = "", translated = "";                                /* declare string variables */
    cout<<"Please enter the original sentence: ";                               /* ask the user to enter a sentence */
    getline(cin, sentence);                                                     /* read complete sentence to sentence */
    for(int i=0;i<sentence.length();i++){                                       /* for each character in sentence */
        if(sentence[i] == ' '){                                                 /* if character = ' ', it denotes the end of a word */
            translated = translated + word.substr (1,string::npos)+ word[0] + "KPU ";   /* relocate first character to end, append "KPU" and append it to translated string */
            word = "";                                                          /* set word = "" */
        }
        else{                                                                   /* otherwise */
            word = word + (char)toupper(sentence[i]);                           /* convert character to upper-case, cast to character and append it to word */
        }
    }
    translated = translated + word.substr (1,string::npos)+ word[0] + "KPU ";   /* for the last word, relocate first character to end, append "KPU" and append it to translated string */
    cout<<"\nTranslated: "<<translated;                                         /* print translated string */
    
    return 0;
}
