Given string stringVal on one line, integer idxStart on a second line, and integer choiceLen on a third line, replace choiceLen characters with "1234", starting at index idxStart. Ex: If the input is: Fuzzy bear 3 4 then the output is: Fuz1234ear Note: Using a pre-defined string function, the solution can be just one line of code. #include #include using namespace std; int main() { string stringVal; int idxStart; int choiceLen; getline(cin, stringVal); cin >> idxStart; cin >> choiceLen; /* Your code goes here */ cout << stringVal << endl; return 0; }

Create a function that determines how many number pairs are embedded in a space-separated string. The first numeric value in the space-separated string represents the count of the numbers, thus, excluded in the pairings. Examples number_pairs("7 1 2 1 2 1 3 2") 2 // (1, 1), (2, 2) number_pairs ("9 10 20 20 10 10 30 50 10 20") 3 // (10, 10), (20, 20), (10, 10) number_pairs("4 2 3 4 1") → 0 // Although two 4's are present, the first one is discounted.

Q1 As do in while code. Two String values are passed as input. Find if the second string s2 is a substring of the first strings1. If it is, print the index of the first occurrence.Else print -1.Inputmake123India123Output4*/#include<iostream>#include<string.h>using namespace std;int isSubstring(string s1, string s2) { int temp,j; for(int i=0;s1[i]!='0円';i++) { j=0; if(s1[i]==s2[j]) { temp=i+1; while(s1[i]==s2[j]) { i++; j++; } if(s2[j]=='0円') { return temp-1; } else { i=temp; temp=0; } } } if(temp==0) return -1;} int main(int argc, char const *argv[]){ string s1,s2; getline(cin,s1); getline(cin,s2); int res = isSubstring(s1,s2); if(res==-1) cout<<res; else cout<<"Found at index: "<<res;..

3. Word Counter Write a function that accepts a pointer to a C-string as an argument and returns the number of words contained in the string. For instance, if the string argument is "Four score and seven years ago" the function should return the number 6. Demonstrate the function in a program that asks the user to input a string then passes it to the fune- tion. The number of words in the string should be displayed on the screen. Optional Exercise: Write an overloaded version of this function that accepts a string clás object as its argument.

// Write a function that takes 1 argument, a string. // It returns true if the string is a palindrome (the same forwards and backwards). // It returns false if the string is not a palindrome. const isPalindrome = (string) => { // your code here... // Examples isPalindrome("cat") // returns false //isPalindrome("level") // returns true }

Code is in C++ Instructions Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Input is as follows highlighted in bold John Doe 333224444 DoeJ 123Password My problem is with my output, i am close with the code, but i have attached what happens on my output and i cannot figure out why? You can see how it prints out multiple times but i am lost? The terminal image is also attached. Thank you! Here is the code: #include <iostream> //include statement(s)#include <iomanip>#include <string> using namespace std; //using namespace statement(s) void getInfo(string info); //void...

When you provide null as an argument to the Split function of a string object, what characters are used as delimiters?

get_nth_comma_in_string(s, n): This function takes a string s and a non-negative integer n as input. It returns the index of the n’th comma in the string s. We will start counting at 0, so if n=0, then the index of the first comma should be returned; if n=1, then the index of the second comma should be returned, and so on. If there is no n’th comma in s, then -1 should be returned. Note: You may use the string find method in this function.

Given string userString on one line, character newChar on a second line, and integer strIndex on a third line, change the character at index strIndex of userString to newChar. Ex: If the input is: garlic Z 0 then the output is: Zarlic Note: Assume the length of string userString is greater than strIndex. #include <iostream> #include <string> using namespace std; int main() { string userString; char newChar; int strIndex; getline(cin, userString); cin >> newChar; cin >> strIndex; /* Your code goes here */ cout << userString << endl; return 0; }

4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is "aBdDEfgHijK" then show_upper should return "BDEHK". It should return the upper-case string - not print it. Do not change anything outside show_upper.
