Need help creating function that capitalizes a char array!

[AndrewGary]

I am stuck on a part of my final project for Introduction to C++ class. This is what it tells me to do.

Write a function called strUpper. This function should accept a pointer to a string as its argument. It should convert each character in the string to an uppercase letter.

This is what I have come up with, but it does not work properly.

#include<iostream>
using namespace std;

void strUpper(char*);

int main()
{

	const int SIZE = 11;
	char test[SIZE];
	cout << "Enter a string: ";
	cin.getline(test, SIZE);
	strUpper(test);
	cout << test;

	
	return 0;
}
void strUpper(char *itest)
{
	int count = 0;
	while (*itest != '\0')
	{
		cout << toupper(*(itest + count));
		count++;
	}
}

Any help with what I'm doing wrong and how to fix it would be much appreciated!

while (*itest != '\0')

When is that loop ever going to end?

Wow I feel stupid.

I changed it, and it still gives me weird output.

#include<iostream>
using namespace std;

void strUpper(char*);

int main()
{

	const int SIZE = 11;
	char test[SIZE];
	cout << "Enter a string: ";
	cin.getline(test, SIZE);
	strUpper(test);
	cout << test;

	
	return 0;
}
void strUpper(char *itest)
{
	int count = 0;
	while ((*(itest + count)) != '\0')
	{
		cout << toupper(*(itest + count));
		count++;
	}
}

The value is returned as an int value

This is what I have come up with.

#include <iostream>
using namespace std;

void capitalize(char*);

int main()
{
	const int SIZE = 11;
	char yeah[SIZE];

	cout << "Enter a string: ";
	cin.getline(yeah, SIZE);
	
	cout << yeah << endl;
	
	capitalize(yeah);

	cout << endl;

	return 0;
}

void capitalize(char *yeah)
{
	int count = 0;
	while((*(yeah + count) != '\0'))
	{
		
		cout << putchar(toupper(*(yeah + count)));
		count++;
	}
}

I can not figure out why it is printing the ASCII code number after each letter. Any explanation or help would be much appreciated!

I figured it out! Thanks for all the help, it is much appreciated!
