I want to make a program counting characters in a sentence .... and it just doesn't work😁....someone can explain to me???

Question

#include <iostream>
using namespace std;

int main() {

char x;
int counter;
while (cin>>x) {
counter += 1;

}
cout<< "there is " << counter << " characters" <<endl;

return 0;
}

Answer 1

I expect you are getting a compiler error because you didn't put a number stating how big the array x is. Your counter isn't initialized so you will get a random result. Reading into an array however many characters it contains, yet you only increment counter by 1. cin will overwrite memory, if you type more characters than x supports.

Answer 2

IBO I can address you to use array of characters instead

Answer 3

I think simple way to count characters in a paragraph is use strlen(i dont know the equivalent of this in c++) just trim the whitespaces and use strlen add 1 since the strlen starts counting at zero like array :)
