assignment statement

Computer

A fundamental statement of all programming languages (except declarative languages) that assigns a new value to a variable. The typical form in Algol-like languages is
$variable : = expression$
where := is read as ‘becomes’; the symbol suggests a left-pointing arrow to signify the conveyance of a value to the variable on the left. Other languages (particularly Basic, C, C++, Java, and Fortran) use = as the assignment operator, e.g.
$a = b + c$
This leads to problems in expressing the concept of equality. Basic, being an unsophisticated language, is able to use = for both purposes; C, C++, and Java use = = for equality and Fortran uses .EQ.
