Among them, expression1 and expression2 are the two expressions to be compared.

int y = 7;

bool result = (x != y); // true

int a = 10;
int b = 10;

bool result = (a != b); // false

Note:

    ##!= is the opposite of the == operator, which means " equal".
  • != can be used for any data type, including basic data types (such as int, float, char) and custom data types (such as classes and structures).
  • != operator has higher precedence than arithmetic operators, but lower precedence than logical operators && and ||.
