Exercise 10

Write a C program to find both the largest and smallest number of an array of integers.

SOURCE CODE:

/*Program to Find Largest and Smallest among set of Numbers*/
#include<stdio.h>
void main()
{
 int a[20],n,i,largest,smallest;
 clrscr();
 printf("Enter number of elements:");
 scanf("%d",&n);
 printf("\nEnter %d elements:",n);
 for(i=0;i<n;i++)
  scanf("%d",&a[i]);
 largest=a[0];
 smallest=a[0];
 for(i=0;i<n;i++)
 {
  if(largest<=a[i])
   largest=a[i];
  if(smallest>=a[i])
   smallest=a[i];
 }
 printf("\nLargest number is %d",largest);
 printf("\nSmallest number is %d",smallest);

}

OUTPUT:

Write C programs illustrating call by value concept.

SOURCE CODE:

/*Program to implement call by value*/

void call_by_val(int,int);

#include<stdio.h>

#include<conio.h>

void main()

{

 int a,b;

 clrscr();

 printf("Enter a,b values:");

 scanf("%d%d",&a,&b);

 printf("\n::Before function calling::\n a=%d \t b=%d",a,b);

 call_by_val(a,b);

 printf("\n::After function calling::\n a=%d \t b=%d",a,b);

}

void call_by_val(int a,int b)

{

 int c;

 c=a;

 a=b;

 b=c;

 printf("\n::In function::\n a=%d \t b=%d",a,b);

}

OUTPUT:

Write a C program illustrating call by reference concept.

SOURCE CODE:

/*Program to implement call by reference*/

void call_by_ref(int*,int*);

#include<stdio.h>

#include<conio.h>

void main()

{

 int a,b;

 clrscr();

 printf("Enter a,b values:");

 scanf("%d%d",&a,&b);

 printf("\n::Before function calling::\n a=%d \t b=%d",a,b);

 call_by_ref(&a,&b);

 printf("\n::After function calling::\n a=%d \t b=%d",a,b);

}

void call_by_ref(int *a,int *b)

{

 int c;

 c=*a;

 *a=*b;

 *b=c;

 printf("\n::In function::\n a=%d \t b=%d",*a,*b);

}

OUTPUT:
