what do we mean by (literal) in C++ ???

Question

⁉

Answer 1

The actual (literal) value of the variable or constant

For example--
int i =0;
bool j = false;
int k = 0;

if(i == j) --> This will return true
if(i === j) --> This will return false (Type is considered)
if(i === k) --> This will return true
