The associativity of operators refers to order in which repeated use of the same operator will be evaluated. For example, the expression 1+2+3 will be evaluated as (1+2)+3 since the "+" operator associates the leftmost operator instances first. In contrast, the statement A = B = C will first perform the B = C assignment, and then the result is assigned to A.

Associativity should not be confused with precedence, which determines which one of different operators will be evaluated first. In the example 1+2_3+4, the multiplication is performed first due to precedence, while the left addition is performed before the rightmost addition due to associativity, causing the expression to be evaluated as (1+(2_3))+4.
