How to grab numbers from string in cpp

// An easier way to extract each character would be:

string s = "abcde"; 
 
for (int i=0; i<s.size(); i++) { 
    cout << s[i];  
} 
// To test if a particular character is an integer, you would do this:

//test if s[i] is an int from 0-9 
if (s[i] <= '9' && s[i] >= '0') { 
    return true; 
}
