Question

Assign searchResult with a pointer to any instance of searchChar in personName.

Answer 1

Answer:  

Here it the solution statement:  

searchResult = strchr(personName, searchChar);  

This statement uses strchr function which is used to find the occurrence of a character (searchChar) in a string (personName). The result is assigned to searchResult.

Headerfile cstring is included in order to use this method.

Explanation:  

Here is the complete program

#include<iostream> //to use input output functions  

#include <cstring> //to use strchr function  

using namespace std; //to access objects like cin cout  

int main() { // start of main() function body  

  char personName[100]; //char type array that holds person name  

  char searchChar; //stores character to be searched in personName

  char* searchResult = nullptr; // pointer. This statement is same as searchResult  = NULL    

  cin.getline(personName, 100); //reads the input string i.e. person name  

  cin >> searchChar;    // reads the value of searchChar which is the character to be searched in personName  

  /* Your solution goes here */  

  searchResult = strchr(personName, searchChar); //find the first occurrence of a searchChar in personName  

  if (searchResult != nullptr) //if searchResult is not equal to nullptr  

  {cout << "Character found." << endl;} //displays character found

  else //if searchResult is equal to null  

  {cout << "Character not found." << endl;} // displays Character not found  

  return 0;}  

For example the user enters the following string as personName  

Albert Johnson  

and user enters the searchChar as:  

J

Then the strchr() searches the first occurrence of J in AlbertJohnson.  

The above program gives the following output:  

Character found.
