Count character occurrences in a string in C++
...heck if c equals '_'
If yes, increase count
EDIT: C++ example code:
int count_underscores(string s) {
int count = 0;
for (int i = 0; i < s.size(); i++)
if (s[i] == '_') count++;
return count;
}
Note that this is code to use together with std::string, if you're using char*, re...
Why can lambdas be better optimized by the compiler than plain functions?

CSS text-overflow: ellipsis; not working?
...alc, the final value is rendered in absolute pixels, which consequentially converts 80% to something like 800px for a 1000px-width container. Therefore, instead of using width: [YOUR PERCENT]%, use width: calc([YOUR PERCENT]%).

cout << str[i];
}
This will print the string character by character. str[i] returns character at index i.
If it is a character array:
char str[6] = "hello";
for (int i = 0; st...
