Q1. Write a program to search a number from a given list using linear and binary
search.
#include<stdio.h>
#inlcude<conio.h>
void main()
{
int arr[10];
int i,j;
int n
int snumber;
int count=0;
printf("Enter the number of element in array");
scanf("%d",&n);
printf("nEnter the element in array");
for(i=0;i<n; i++)
{
scanf("%d",&arr[i]);
}
printf("nenter the search element");
scanf("%d",&snumber);

if(arr[i]==snumber)
{
count=1;
printf("value is found");
break;
}
}
if(count==0)
printf("value is not found");
getch();
}

scanf("%d",&n);
high=n;
printf("Enter the value in sorted formn");
for(i=0;i<n;i++)
{
scanf("%d",&b[i]);
}
printf("Enter the value which you have to find");
scanf("%d",&value);
pos=binary(low,high,value);
//printf("n in location %d th",pos);
