What does <= mean in c++

The <= operator in C is used to compare whether two expressions are equal or less than each other. If the expression on the left is less than or equal to the expression on the right, it returns true, otherwise it returns false. Syntax: Expression 1 <= Expression 2 Priority: higher than arithmetic operators, lower than logical operators Purpose: compare values, limit loops, check whether the index is out of range, determine whether the value is within a specific range

<= operator in C

##<= operator meaning

The <= operator in C is a relational operator used to compare whether two expressions are equal or less than. Its meaning is that if the expression on the left is less than or equal to the expression on the right, it returns true, otherwise it returns false.

<= The syntax of the operator

<= The syntax of the operator is as follows:

表达式1 <= 表达式2

Among them, expression 1 and expression 2 is the value or expression to be compared.

<= The precedence of the operator

<= The precedence of the operator is higher than the arithmetic operator (such as, -, *, /), but Below logical operators (such as &&, ||).

Examples of<= Operator

Here are some examples of <= operator:

5 <= 10 // true
10 <= 10 // true
15 <= 10 // false
"a" <= "b" // true

<= Operation Other uses of the operator

In addition to comparing two values, the <= operator can also be used for other purposes, such as:

Limit the number of loop iterations.
• Check whether the index in the array or collection is out of range.
• Determine whether a value belongs to a specific range.
