Question

Write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use dynamic arrays to store the string.)

my code below:

/*
Your code from Chapter 8, exercise 5 is below.

Rewrite the following code to using dynamic arrays.
*/

#include <iostream>

#include <cstring>

#include <cctype>

using namespace std;

int main()
{

//char str[81];

//creating memory for str array of size 80 using dynamic memory allocation

char *str = new char[80];

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);

//displaying each character in upper case letter

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

cout << static_cast<char>(toupper(*(str+i)));
cout << endl;

return 0;
}

keeping getting it wrong need help not sure what im doing wrong

Input 11 Hello World Output Enter a string: 11 String in upper case letters is: 11 Hello World
Test Case Incomplete To Upper Test 2 Input 14 I love to code Output Enter a string: 14 String in upper case letters is: 14 I love to code

Answer 1

Below is the code which I wrote:

Quite similar to what you've written but used different way for taking string input and typecasting integer to character. That's working as expected.

Below is the output:
