Variable Arguments in CPrevious Quiz Next Sometimes, you may come across a situation, when you want to have a function that can accept a variable number of arguments (parameters) instead of a predefined number of arguments. The C programming language provides a solution for this situation....
va_start( arguments, num );// Initializing arguments to store all values after num for(intx = 0; x < num; x++ )// Loop until all numbers are added sum +=va_arg( arguments,double);// Adds the next value in argument list to sum. ...

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 ...
while variables store information that can then be used within those functions or methods. Arguments must also be passed into functions, whereas variables can be declared outside or within functions. And arguments must match up exactly in terms of data type, while variables do not always need to...
SourceC vprintf Documentation This tutorial has explored the vprintf function and its variants, demonstrating how to create flexible formatted output functions in C. By understanding these techniques, you can build more robust and maintainable code that handles variable arguments safely and efficiently. ...
This program willdemonstrate example of Variable Arguments, in this program we will create a user define function for calculating sum of N arguments, using Variable Arguments we can pass multiple arguments in the function. Example of Variable Arguments using C program ...
Parameters or Arguments ap A variable argument list. type The type of the argument. Returns The va_arg function returns the value of the argument. Required Header In the C Language, the required header for the va_arg function is: #include <stdarg.h> ...
In addition, only local variables and the arguments which are passed to the functions can be declared as register variables. Moreover, declaring a variable as register does not guarantee that it will be a treated as register variable. In that case, it will be treated as an automatic variable...
Variable arguments or varargs methods allows method to take as many number of arguments you want. Variable arguments should be last parameter.
