Rules to pass an array to function

The function must be called by passing only

the name of the array.

In the function definition, the formal

parameters must be an array type, the size of

the array does not need to be specified.

The function prototype must show that the

argument is an array.

One-Dimensional array

int a[100];

//Funtion call

largest(a,n);//funtion definition

int largest(int x[ ], int size)

Write a C function which takes an array of

integers as its argument and returns the

average of all array elements. Also write the

associated main function, which reads the

array and prints the average.

#include

#include

float avg(int,int[]);// function declaration

main()

{

int i,a[100],n;

float avg1;

clrscr();

printf("Enter size of array \n");

scanf("%d",&n);printf("Enter array a %d elements\n",n);

for(i=0;i


7/26

avg1=avg(n,a);// function call

printf("average=%f",avg1);

getch();}

float avg(int s,int x[])//function defintion

{

float i,sum=0,avg2;

for(i=0;i

Write a c function which takes array of N

integers and to sort them using selection sort.

Use it in the main function to sort N array

elements using selection sort technique.


9/26

#include

#include

void ssort(int,int[]);

int i,j,pos;

main()

{

int a[100],n;clrscr();

printf("Enter Array size\n");

scanf("%d",&n);

printf("Enter %d elements\n",n);for(i=0;i


10/26

ssort(n,a);printf("The sorted array is \n");

for(i=0;i


11/26

void ssort(int s,int x[])

{ int temp;

for(i=0;i


12/26

Write a function that finds the smallest of N

numbers in an array. Use it in a main function

to find the smallest of arrays A,B,C, and D each

with N elements.

Write a C functions

* to read N array elements* to print N array elements

* to sort N array elements in ascending order

using bubble sort.Using these functions write a C program to sort

A, B and C arrays of N elements.
