Write a function that searches for a particular character in a string using the following header: void search(string& s, char& key) Write a test program that prompts the user to enter the string and a character and displays if the character is found.

The following functions are all intended to check whether a string representing a dna sequence contains any characters that are not 'a','c','g','t', 'A', 'C', 'G', or 'T'. At least some of these functions are wrong. Which ones are correct? A) def valid_dna1(dna):     for c in dna:         if c in 'acgtACGT':             return True         else:             return False B) def valid_dna3(dna):     for c in dna:         flag = c in 'acgtACGT'     return flag C)   def valid_dna4(dna):     for c in dna:         if not c in 'acgtACGT':             return False     return True -------------------------------------------------------------------------------------------------------------------------------------------------------- valid_dna1 only valid_dna4 only None of them. valid_dna1, and valid_dna4 only

String.ParseInt(m); will convert the integer value of m to a String     True   False

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.

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…
