boolean expression in c programming

 

 

 

 

This page helps you understand how C treats boolean expressions when implementing these programming constructs in C.Operators and expression forms in C are largely the same as in C. One difference is that relational, equality, and logical expressions evaluate as bool expressions. An expression in a c program is anything which needs to be evaluated, a condition, validity of an array, validity of memory etc. When the expression evaluated to only and only 2 values 0 or 1, then it becomes a boolean expression.
