Check for spaces?

How can I check if the current character is a space or not? I need to print "space" if there's a space. I couldn't get an if statement to work. https://code.sololearn.com/c4ijn3MBIiP6/?ref=app

You need to use single quotes for chars and double quotes for strings

An alternative, add cctype header; #include <cctype> Then, inside your loop, check for whitespace with std::isspace() to verify whether the said character is classified as a whitespace. if(std::isspace(str[i]) // whitespace character else // non whitespace Reference: https://en.cppreference.com/w/cpp/string/byte/isspace

Why didn't double quotes work?

[meta, note] Chars from strings are numeric* so this also works. if(str[i]!= 32) { * signed
