Is if ( c ) the same as if ( c == 0 ) in C++?

The conditions are evaluated to a Boolean value, which should be either TRUE or FALSE. If the condition is found to be TRUE, the corresponding code will be executed, and there will be no other conditions to be evaluated.
You can combine two or more conditional expressions on the IF statement. ISPF evaluates the conditional expressions on the IF statement from left to right, starting with the first expression and proceeding to the next and subsequent expressions on the IF statement until processing is complete.
The block of code inside the if statement is executed is the condition evaluates to true.
Syntax. In both forms of the if statement, the expressions, which can have any value except a structure, are evaluated, including all side effects. In the first form of the syntax, if expression is true (nonzero), statement is executed. If expression is false, statement is ignored.
No, if (c) is the same as if (c != 0). And if (!c) is the same as if (c == 0).

I'll break from the pack on this one... "if (c)" is closest to "if (((bool)c) == true)". For integer types, this means "if (c != 0)". As others have pointed out, overloading operator != can cause some strangeness but so can overloading "operator bool()" unless I am mistaken.
