In C language, && and & are both logical operators, but there are the following differences: && has a higher priority than &; && is left associative, & is right associative; && returns a Boolean value, & returns an integer value; && short-circuit evaluation, & does not short-circuit evaluation.
The difference between && and & in C language
In C language, && and & are both logical operations symbol, used to operate on Boolean values. However, there are several key differences between them:
1. Operation priority
2. Associativity
3. Operation result The operation result of
4. Short-circuit evaluation
Example
The following code example demonstrates the difference between these two operators:
int a = 1, b = 0;
printf("&&: %d\n", a && b); // 输出: 0 (假)
printf("& : %d\n", a & b); // 输出: 0 (0)In the first example , since a is true but b is false, the && expression evaluates to false. In the second example, since a is true and b is false, the & expression evaluates to 0 (an integer value).
