This operators also known as Bitwise negation and one’s compliment operator in C language, it is a Unary operator in C and C++, it converts (inverse) individual bits from 0 to 1 and 1 to 0.For example: there is a variable x with value 0xAA (in binary 1010 1010), ~x will be ...
Unary Operator in C is used to produce a new value by acting upon a single operand. All unary operators are having equal precedence from right side to left side associativity. Unary minus(-), unary plus(+), prefix increment(++a) and decrement(–a), postfix increment(a++) and decrement(...
在bash脚本中,遇到“bash: [: !=: unary operator expected”错误通常是因为在条件判断语句中,变量没有正确处理或者语法使用不当。以下是对该问题的详细分析和解决方法: 1. 错误原因分析 变量未定义或为空:当使用[ $variable != "value" ]这种语法时,如果$variable未定义或为空,那么表达式会变成[ != "value...
