0 what does it mean in c

I believe you can do this using a single iteration I am not sure if there is a built-in function in Objective-C to do that — Ivaylo Strandjev. Since Objective-C is a strict superset of C this constant is retained. Jack Jack k 27 27 gold badges silver badges bronze badges.

C does not specify the number of bits in a char. Yup, you're right. Fixing the anwer — Jack. But how's that relevant? Did I miss an edit to this answer?

It is use to identify whether there is null present in the string or not while performing string oeration. Read More. Sheela 18 Nov marks end of string. Arpita 17 Nov it is used to show that the string is completed. N 16 Nov it is mainly used in string type. In strings by default takes the null charater.

So in C programming language string is basically a character array. For more information, see Examples of Lambda Expressions. You can use auto , together with the decltype type specifier, to help write template libraries.

Use auto and decltype to declare a template function whose return type depends on the types of its template arguments. Or, use auto and decltype to declare a template function that wraps a call to another function, and then returns whatever is the return type of that other function. For more information, see decltype. Note that using auto drops references, const qualifiers, and volatile qualifiers. Consider the following example:. In the previous example, myAuto is an int , not an int reference, so the output is 11 11 , not 11 12 as would be the case if the reference qualifier had not been dropped by auto.

The following code example shows how to initialize an auto variable using braces. Note the difference between B and C and between A and E. The following table lists the restrictions on the use of the auto keyword, and the corresponding diagnostic error message that the compiler emits. These code fragments illustrate some of the ways in which the auto keyword can be used.

The following declarations are equivalent. In the first statement, variable j is declared to be type int. In the second statement, variable k is deduced to be type int because the initialization expression 0 is an integer.

The following declarations are equivalent, but the second declaration is simpler than the first. One of the most compelling reasons to use the auto keyword is simplicity. The following code fragment declares the type of variables iter and elem when the for and range for loops start.

The following code fragment uses the new operator and pointer declaration to declare pointers. The next code fragment declares multiple symbols in each declaration statement.
