Answer 1

Let's declare a boolean variable and a char variable and compare the two:

bool var1 = true;
char var2 = 'x';

Boolean variable 'var1' now stores the value of 'true' or '1'. Basically, we use boolean to evaluate conditional statements. Boolean variables can only store values 'true' or 'false'.

cout << var1;
// outputs 1

Char variable 'var2' now stores the character 'x'. As described, char variable is used to store single characters to be used in your program later on.

cout << var2;
// outputs x
