C Program to Search an Element in an Array using Function

Here we are going to write a c program to search an element in an array using function. There are many searching techniques like Linear Search, Binary Search etc. We will do this program using linear search method.

First we will create a function named search() of void return type and it will take two integers one array and other is the number which we want to search. Then within that function we will check whether the given number is present in the array or not. If found we will return the index and if not we display "Number not found" print the pattern. Then in main() function we will call the search() function, that's it. Now lets code it.

C Program to Search an Element in an Array using Function 

#include <stdio.h>

void search(int arr[], int n){
    int c=0;
    for(int i=0;i<n; i++){
         if(arr[i]==n){
            printf("Number found at %d", i);
            c++;
            break;
            
         }
     }
     if(c==0){
         printf("Number not found!");
     }
}

int main(){
   int n;
   int arr[]={1,2,3,4,5,6,7,8};
   printf("Enter number to find: ");
   scanf("%d",&n);
   search (arr,n);
   return 0;
}

Output

Enter number to find: 7
Number found at 6
