C++ String Exercises: Remove a word from a given string
C++ String: Exercise-34 with Solution
Write a C++ program that removes a specific word from a given string. Return the updated string.
Test Data:
("Exercises Practice Solution", "Solution") -> "Exercises Practice"
("Exercises Practice Solution", "Practice ") -> "Exercises Solution"
("Exercises Practice Solution", " Solution") -> " Practice Solution"
Sample Solution:
C++ Code:
#include <bits/stdc++.h>
using namespace std;
string test(std::string s, std::string w)
{
while (s.find(w) != string::npos)
s.replace(s.find(w), w.length(), "");
return s;
}
int main()
{
string text = "Exercises Practice Solution";
string word ="Solution";
cout << "String: " << text;
cout << "\nWord to remove: " << word;
cout << "\nNew string, after removing the said word:\n";
cout << test(text, word) << endl;
word ="Practice";
cout << "\nString: " << text;
cout << "\nWord to remove: " << word;
cout << "\nNew string, after removing the said word:\n";
cout << test(text, word) << endl;
word ="Exercises";
cout << "\nString: " << text;
cout << "\nWord to remove: " << word;
cout << "\nNew string, after removing the said word:\n";
cout << test(text, word) << endl;
}
Sample Output:
String: Exercises Practice Solution Word to remove: Solution New string, after removing the said word: Exercises Practice String: Exercises Practice Solution Word to remove: Practice New string, after removing the said word: Exercises Solution String: Exercises Practice Solution Word to remove: Exercises New string, after removing the said word: Practice Solution
