   • What does if (variable) mean in C language?

     Top Answer

     Answered Jan 01, 2020 · 2 votes

     An if statement always tests to see if the expression inside the parentheses evaluates to true.

     In this case, var is an positive integer, so it evaluates to true. Since 0 always evaluates to false, as soon as var = 0 the if statement evaluates to false and the loop exits.

     Note that if(var) is not specific to C (re the question title), it applies to many languages.

   • What does `return x ? : 1` mean in C language?

     Top Answer

     Answered Mar 18, 2015 · 16 votes

     This behavior is not mentioned in C standard. Its a GCC extension.

     The middle operand in a conditional expression may be omitted. Then if the first operand is nonzero, its value is the value of the conditional expression.

     Therefore, the expression

     x ? : y-

     has the value of x if that is nonzero; otherwise, the value of y.

     This example is perfectly equivalent to

     x ? x : y -

     In this simple case, the ability to omit the middle operand is not especially useful. When it becomes useful is when the first operand does, or may (if it is a macro argument), contain a side effect. Then repeating the operand in the middle would perform the side effect twice. Omitting the middle operand uses the value already computed without the undesirable effects of recomputing it.

   • what does if(i-2) mean in C language?

     Top Answer

     Answered Jun 18, 2017 · 2 votes

     The statement under an if is executed if the controlling expression is true. In C, an expression that evaluates to 0 is considered false, while any other value is considered true.

     So if (i-2) means the printf will get executed if i-2 is non-zero, i.e. when i is not equal to 2.

   • What does if (! variable_name) mean in c language

     Answered Dec 19, 2012 · 10 votes

     It is equivalent to:

     if (!pid != 0) /* ... */-

     And then:

     if (pid == 0) /* ... */

     C11 (n1570), § 6.5.3.3 Unary arithmetic operators

     The result of the logical negation operator ! is 0 if the value of its operand compares unequal to 0, 1 if the value of its operand compares equal to 0. The result has type int. The expression !E is equivalent to (0==E).

     if(!pid)

     Is as you wrote:

     is

     The !-operator negates a logical condition.

     In C, a numerical value of 0 is considered a logical false, any other numerical value a logical true. The !-operator negates a logical condition, so when pid is 0 it's true and when pid is not 0, it's false.

     You could read it as "when there is no pid".
