Objective :

Variadic functions are functions which take a variable number of arguments. In C programming, a variadic function will contribute to the flexibility of the program that you are developing.

The declaration of a variadic function starts with the declaration of at least one named variable, and uses an ellipsis as the last parameter, e.g.

int printf(const char* format, …);

In this problem, you will implement three variadic functions named sum(), min() and max() to calculate sums, minima, maxima of a variable number of arguments. The first argument passed to the variadic function is the count of the number of arguments, which is followed by the arguments themselves.

 

Task:

In this problem, you will implement three variadic functions named sum(), min() and max() to calculate sums, minima, maxima of a variable number of arguments. The first argument passed to the variadic function is the count of the number of arguments, which is followed by the arguments themselves.

Input Format:

  • The first line of the input consists of an integer number_of_test_cases.
  • Each test case tests the logic of your code by sending a test implementation of 3, 5 and 10 elements respectively.
  • You can test your code against sample/custom input.
  • The error log prints the parameters which are passed to the test implementation. It also prints the sum, minimum element and maximum element corresponding to your code.

Sample Input 0:

Solution Solution :

int sum(int count, …)
{
va_list arr;
int t = 0;
va_start(arr, count);
while(count–){
t += va_arg(arr, int);
}
return t;
}

int min(int count, …)
{
va_list arr;
int mn = MIN_ELEMENT;
va_start(arr, count);
while(count–){
if(mn > va_arg(arr, int))
mn = va_arg(arr, int);
}
return mn;
}

int max(int count, …)
{
va_list arr;
int mx = MAX_ELEMENT;
va_start(arr, count);
while(count–){
if(mx < va_arg(arr, int))
mx = va_arg(arr, int);
}
return mx;
}

What is #Include<stdio.h> ?

#include<stdio.h> is used to included header file in c programming language. It is a Mandetory. It is also Compiler Directives to Include INPUT/OUTPUT related function in our Program. TheĀ stdio.hĀ is a file with “.h” extension which is contain the prototypes [not definition] of standard input-output functions used in c program.

What is int main() ?

ā€˜int mainā€™ means our perform must come thusme whole number at the top of the execution and that we do so by returning zero at the top of the program. zero is that the normal for the ā€œsuccessful execution of the programā€.

What is Printf and Scanf ?

The printf() and scanf() functions area unit used for input and output in C language. each functions area unit inherent library functions, outlined in stdio.h (header file).

What is Compiler ?

The language processor that reads the whole program written in application-oriented language as a full in one go and interprets it into identical program in machine language is named a Compiler. Example: C, C++, C#, Java. compilers/assemblers area unit themselves package, and reside where they were put in on the pc. that additionally implies that you just will have as many/few of every as you wish.

How “Variadic Functions in C – HackerRank Solution” program works?

  • The #include is a preprocessor command that tells the compiler to include the contents of stdio.h (standard input and output) file in the program.
  • The stdio.h file contains functions such as scanf() and printf() to take input and display output respectively.
  • If you use the printf() function without writing #include <stdio.h>, the program will not compile.
  • The execution of a C program starts from the main() function.
  • printf() is a library function to send formatted output to the screen. In this program, printf() displays Hello, World! in C text on the screen.
  • TheĀ return 0;Ā statement is theĀ “Exit status”Ā of the program. In simple terms, the program ends with this statement.

The #include could be a preprocessor command that tells the compiler to incorporate the contents of stdio.h (standard input and output) enter the program.
The stdio.h file contains functions like scanf() and printf() to require input and show output severally.
If you utilize the printf() perform while not writing #include , the program won’t compile.
The execution of a program starts from the main() perform.
printf() could be a library perform to send formatted output to the screen. during this program, printf() displays hello, World! in C text on the screen.
TheĀ return 0;Ā statement is theĀ “Exit status” of the program. In straightforward terms, the program ends with this statement.
