Linear Search by R4R Team

Array:

Array is the collection of different values having same data type.
-We have a integer Array that having all integer values.
-Character array is known as String.

How we Search in Array?
-There are two possible way to search anything in Array's
1. Linear Search
2. Binary Search(applicable on sorted data)

program-

#include < stdio.h>
int main()
{
int a[100],n,i,num;
printf("Number of elements in array ?\n");
scanf("%d",&n);
printf("Enter %d number in array\n",n);
for(i=0;i< n;i++){
scanf("%d",&a[i]);
}
printf("Enter number to search in the array\n");
scanf("%d",&num);
for(i=0;i< n;i++)
{
if(a[i]==num){
printf("Number is at %dth position",i+1);
break;
}
}
if(i==n)
{
printf("Number is not in array\n");
}
}


output-

Number of elements in array ?
5
Enter 5 number in array
1 2 3 4 5
Enter number to search in the array
4
Number is at 4th position

Number of elements in array ?
5
Enter 5 number in array
1 2 3 4 5
Enter number to search in the array
6
Number is not in array

-In this program, firstly we take a input in array, and then take a input of number that we search in tha array.
-Traverse whole array and check for each value if value matched then break the loop otherwise continue until the length of the array.
