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 personNa,e
/* 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.
