can anyone help me type this program using functions

//write down a program that accepts 50 char values from user. The value can be anything char from the

key board. The program counts capitals, smalls and numeric values (0-9) separately, . It has to use a

switch structure to increment counts. It has to use an if else to decide b/w different char types It

displays the count each type at the end.

//now write it using a function, the function determines the type of the character and

returns an integer appropriately e.g. 1 for capitals, 2 for smalls, 3 for numeric values and -1 for all

others. rest of the program lies in the main.

#include <iostream>

#include <string>

using namespace std;

int main()

{

int numerical_count{};

int uppercase_count{};

int lowercase_count{};

char ch = 50;

int i;

std::string result;

result.resize(50); 

for (i = 0; i < 50; i++)

{

std::cin >> result[i];

for (const auto& ch : result)

{

if (ch >= '0' && ch <= '9')

numerical_count++;

else if (ch >= 'A' && ch <= 'Z')

uppercase_count++;

else if (ch >= 'a' && ch <= 'z')

lowercase_count++;

}

std::cout << "# numerical: " << numerical_count << std::endl;

std::cout << "# uppercase: " << uppercase_count << std::endl;

std::cout << "# lowercase: " << lowercase_count << std::endl;

}

switch (ch)

{

case '0': case '1': case '2': case '3': case '4':
