Please help me with my code

Question

Can you please tell me where I got it wrong? The code is for "Average Word Length".

#include <iostream>
#include <cmath>
using namespace std;

int main() {
string s;
float k = 0;
float j = 1;
getline(cin, s);
for (int i = 0; i < s.length(); i++) {
if (s[i]!=' ') {
k+=1;
}
else {
j+=1;
}
}
cout << ceil(k/j);
return 0;
}

Answer 1

Your counting include special characters like '?'
Just count the letters and divide by no. of space

#include <iostream>
#include <cmath>
using namespace std;

int main() {
string s;
float k = 0;
float j = 1;
getline(cin, s);
for (int i = 0; i < s.length(); i++) {
if ((s[i]>='a' && s[i]<='z') || (s[i]>='A' && s[i]<='Z')) {
k+=1;
}
if(s[i]==' ') {
j+=1;
}
}
cout << ceil(k/j);
return 0;
}

Arun Ruban SJ So, I just need to count the letters in the string?
