Question

Write a C++ program for the instructions below. Please read the instructions carefully and make sure they are followed correctly.  

please put comment with code! and please do not just copy other solutions.

1. write the code using function

2. Please try to implement a function after the main function and provide prototype before main function.

Total Characters in String Array 10 points Problem 2 Declare a string array of size 5. Prompt the user enter five strings that are stored in the array. Afterwards, prompt the user to enter a character. Write a function that expects the following three parameters: an array, the size of the array, anda char. The function counts the number of occurrences of that char in all of the strings stored in the array and returns it. Call that function from the main and output the returned value Example Enter five items. Item 1 hello Item 2: C++ Item 3: Wednesday Item 4 It's a great day Item 5 goodbye Target: e The char e was found 5 times. Note: Don't forget to include <string>. You may only use the .length() function on a string variable to get the number of characters in a string, e.g. str.length(). Use array syntax on a string variable to access any char by index, e.g.: assuming a string variable named strthat stores "hello", str[1] would return 'e'.

Answer 1

Here is code:

#include <iostream>

#include <string>

using namespace std;

/*

countOccurrences return integer that number of times the key repeated in str array

*/

int countOccurrences(string *strs, int size, char key)

{

int count = 0;

// loop size times

for (int i = 0; i < size; i++)

{

// loop each string of item and count occurrence of char

for (int j = 0; j < strs[i].length(); j++)

{

if (strs[i][j] == key)

{

count++;

}

}

}

return count;

}

int main()

{

const int size = 5; // size of items

string str[size];

char c;

int count = 0;

// read string input from user

cout << "Enter five items." << endl;

for (int i = 0; i < size; i++)

{

cout << "Item " << i + 1 << ": ";

getline(cin, str[i]);

}

// read target char

cout << "\nTarget: ";

cin >> c;

// get the count of number of times occurence of 'c' in str array

count = countOccurrences(str, size, c);

cout << "The char " << c << " was found " << count << " times." << endl;

} // End of main()

Output:

Enter five items. Item 1: hello Item 2: C++ Item 3: Wednesday Item 4: It's a great day Item 5: goodbye Target: The char e was found 5 times.
