#include <iostream>
#include <string>
using namespace std;

string askString(string s);
string reverseCase(string s);

int main(){

string s;

//this function asks a string from the user
askString(s);

//this function converts small letters to capital, and capital to small
reverseCase(s);

return 0;
}
 
string askString(string s){
	cout << "Type a string: ";
		cin >> s;
}

string reversCase(string s){
	if(s[i] >= 'a' && s[i] <= 'z'){
    //s[i] is lowercase
