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

if(str[i] == ' ')

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

if(str[i]!= 32) {
