\nwhat does it mean in c++

In C, != means "not equal to" and is used to compare whether two operands are not equal, and the result is true or false. The syntax is bool != (expression1, expression2), where expression1 and expression2 are the expressions to be compared.

The meaning of != in C

!= is a logical operator in C, which means "not equal". It compares two operands and returns true if they are not equal, false otherwise.

Syntax

<code class="cpp">bool != (expression1, expression2)</code>

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

Example

<code class="cpp">int x = 5;
int y = 7;

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

int a = 10;
int b = 10;

bool result = (a != b); // false</code>

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 ||.
