Cannot type in CMD

[WillDesigned]

I recently came across the issue of not being able to type in my cmd console. I was working on a project in MSV; while starting a new one I was unable to type in the console. *After compiling with no errors.

#include <iostream>

//@author Will A. Training Exercise Grade Programming

int main()
{
	int grade = NULL;
	bool repeat = true;

	std::cout<<"Grade Programming Created By Will A.\n";

	while(repeat)
	{
		if((grade <=100)&&(grade >=90))
		{
			std::cout<<"Your grade is an A\n";
		}
	}
}

Although in another project I worked on previously I still may type in the console.

You aren't asking for any input?

[WillDesigned]

Well, I added

std::cout<<"Your grade is an A\n";
			std::cin>>grade;

I'm most likely completely wrong, sorry for my ignorance.

If you don't mind assisting me a tad more.

[firedraco]

So it still doesn't let you type with that there?

That's rather odd, are you sure the window is in focus?

[WillDesigned]

How do you mean? ...in focus?

Can you please post your code WITH WillDesigned's code inserted.

start with something like this,,,,

#include <iostream>

using namespace std;

//@author Will A. Training Exercise Grade Programming

int main()
{
	int grade = NULL;
	char repeat = 'y';

	cout<<"Grade Programming Created By Will A" << endl;

	while(repeat == 'y')
	{
		cout<<"Enter your grade:" << endl;
		cin >> grade;

		if((grade <=100)&&(grade >=90))
		{
			cout<<"Your grade is an A"<< endl;
		}

		cout<<"Enter a new grade? Y OR N:" << endl;
		cin >> repeat;
		system("cls");
	}
	return 0;
}

Here is what I came up with very quickly. The while loop is currently unnecessary but I left it in for your sake.

#include <iostream>

//@author Will A. Training Exercise Grade Programming

int main()
{
	int grade = NULL;
	bool repeat = true;

	std::cout<<"Grade Programming Created By Will A.\n";
	std::cout << "Enter your grade: ";
	std::cin >> grade;
	while(repeat){
		if((grade <=100)&&(grade >=90))
		{
			std::cout<<"Your grade is an A\n";
		}
	}
}

@CodeWeaver @joneele @firedraco

Thank you for the help! Glad to know people are considerate unlike other forums I've previously was part of.

[firedraco]

Ah, I see. std::cin was inside your if check, which is never true because grade is 0 and is never changed.

Btw:

int grade = NULL;

This sets grade to 0, *not* something like NULL or NaN. You should only use NULL with pointers.

[WillDesigned]

Yeah. Sorry about not presenting the full code.


I asked my friend whom has experience in c++. (Early till this moment)
He said it doesn't make much a difference in this case. Thanks for telling me that, I'll make sure to use that to the best of my knowledge.
