\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
bool != (expression1, expression2)
Among them, expression1
and expression2
are the two expressions to be compared.
Example
int x = 5; 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 ||.
