Number input only, no text

Question

//-------------------------
int Input =0;

cin >> Input;
cout << "Your input is: " << Input;
//-------------------------

My question is, how can I make the Input variable accept number only, and not text?

Because when I input text, it says error, I want to make a code without error if possible.

Jonathan Jundarino if you will type any String it will give you error becoz you defined type of Variable int type .
If u want to take input String then u can write like this
char str[20];
cin>>str ;

Answer 4

You can put cin in if statement. It will evaluate true if the input is satisfied and correct, else false.

int z;
if(cin >> z)
//Code for input number
else
//Code for not input number
