C++ "qwerty" is a string commonly found in weak passwords. Replace the occurrences of "qwerty" in passwdStr with "mvhnkl". Ex: If the input is qwerty4<9k@VHP75J8&qwerty, then the output is: Adjusted password: mvhnkl4<9k@VHP75J8&mvhnkl Note: string.find(item) returns the index of the first occurrence of item in string. If no occurrence is found, then the function returns string::npos. string.replace(indx, num, subStr) replaces characters at indices indx to indx+num-1 with a copy of subStr. #include #include using namespace std; int main() { string passwdStr; int i; cin >> passwdStr; i = 0; cout << "Enter password: "; getline(cin, passwdStr); while (passwdStr.find("qwerty") != string::npos) { int i = passwdStr.find("qwerty"); passwdStr.replace(int i, 6, "mvhnkl"); } cout << "Adjusted password: " << passwdStr << endl; return 0; }

C++
"qwerty" is a string commonly found in weak passwords. Replace the occurrences of "qwerty" in passwdStr with "mvhnkl".
Ex: If the input is qwerty4<9k@VHP75J8&qwerty, then the output is:
Adjusted password: mvhnkl4<9k@VHP75J8&mvhnkl
Note:
- string.find(item) returns the index of the first occurrence of item in string. If no occurrence is found, then the function returns string::npos.
- string.replace(indx, num, subStr) replaces characters at indices indx to indx+num-1 with a copy of subStr.
#include <iostream>
#include <string>
using namespace std;
int main() {
string passwdStr;
int i;
cin >> passwdStr;
i = 0;
cout << "Enter password: ";
getline(cin, passwdStr);
while (passwdStr.find("qwerty") != string::npos) {
int i = passwdStr.find("qwerty");
passwdStr.replace(int i, 6, "mvhnkl");
}
cout << "Adjusted password: " << passwdStr << endl;
return 0;
}
