Write a program that prompts the user to input a string and outputs the string in uppercase letters using dynamic arrays. C++.

Code I have:

#include #include #include using namespace std;

int main() { char str[81];

int len;

int i;

cout << "Enter a string: "; cin.get(str, 80); cout << endl; cout << "String in upper case letters is:" << endl;

len = strlen(str); for (i = 0; i < len; i++) cout << static_cast(toupper(str[i])); cout << endl;

return 0; }

Output must have "Hello"
