Assign searchResult with a pointer to any instance of searchChar in personName. #include
#include
int main(void) {
char personName[100] = "Albert Johnson";
char searchChar = 'J';
char* searchResult = NULL;
/* Your solution goes here */
if (searchResult != NULL) {
printf("Character found.\n");
}
else {
printf("Character not found.\n");
}
return 0;
}

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.

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
