Variable argument lists in C functions How to properly iterate
You re doing a test in that while of a value but at the same time creating a side effect namely reading in the next argument As I said this is considered pretty normal yea idiomatic in C because a lot of C programmers do this I think there are even examples of similar code in K R By personal preference I d probably rewrite this as
Variable Length Argument in C GeeksforGeeks, Read Courses Practice Variable length argument is a feature that allows a function to receive any number of arguments There are situations where we want a function to handle variable number of arguments according to requirement 1 Sum of given numbers 2 Minimum of given numbers and many more Variable number of arguments are represented
How to write functions with variable arguments in C
If you nevertheless need such a function take a look at this example the point is va list double FindAverage int nCount long lSum 0 We access the ellipses through a va list so let s declare one va list list We initialize the va list using va start The first parameter is the list to initialize
Declaring variables in the arguments to a function in C, 5 Besides block scope declarations in C99 there are basically two other ways to declare variables that are by definition restricted to the statement in which they occur Compound literals are of the form type name initializers and declare a local variable that lives in the current block
Variadic functions cppreference
Variadic functions cppreference, Variadic functions are functions e g printf which take a variable number of arguments The declaration of a variadic function uses an ellipsis as the last parameter e g int printf const char format See variadic arguments for additional detail on the syntax and automatic argument conversions Accessing the variadic arguments from the function body uses the following library facilities

C Variable arguments
C Variable arguments Variable arguments Variable arguments are used by functions in the printf family printf fprintf etc and others to allow a function to be called with a different number of arguments each time hence the name varargs To implement functions using the variable arguments feature use include stdarg h To call functions which take a variable number of arguments ensure there is a full
Function Parameters Arguments In Python Arguments Parameters In
A function that takes a variable number of arguments is called a variadic function In C a variadic function must specify at least one fixed argument with an explicitly declared data type Additional arguments can follow and can vary in both quantity and data type In the function header declare the fixed parameters in the normal way then Variable Number of Arguments GNU C Language Manual . In the journey of learning C functions we learned many concepts related to functions We learned to define our own function passing arguments to a function returning value from a function recursive function etc In this chapter I will talk something interesting about passing variable length arguments to a function C style variadic functions are supported in C However most C libraries use an alternative idiom e g whereas the c printf function takes variable arguments the c cout object uses overloading which addresses type safety and ADTs perhaps at the cost of implementation simpli
