equals sign

In programming, the equals sign (=) is used for equality and copying. For example, if x = 0 means "if X is equal to zero;" however x = 0 means "copy the value zero into the variable X." Double equals signs (==) means equals to in C. For example, if (x == 0) means if X is equal to zero. The unusual use of the double equals sign causes many errors in C programming.
