# Linear Search in C, C++, JAVA, PHP, Python3 and C#

Today, We want to share with you linear search in c, C++, JAVA, PHP, Python3 and C#.In this post we will show you search program in c using flag, hear for search in data structure we will give you demo and example for implement.In this post, we will learn about int to string c++ with an example.

## Linear Search Examples :

There are the Following The simple About How to Implement Linear Search in C? Full Information With Example and source code.

As I will cover this Post with live Working example to develop Linear Search Algorithm, so the C Program for finding number in search is used for this example is following below.

Query: Given simple Example of an array productids[] of n elements, fully source code a function to search a given element x in productids[].

### Using C++ code Example

```#include <iostream>
using namespace std;

int linearsearchmyfun(int productids[], int n, int x)
{
int i;
for (i = 0; i < n; i++)
if (productids[i] == x)
return i;
return -1;
}

int main(void)
{
int productids[] = { 2, 3, 4, 10, 40 };
int x = 10;
int n = sizeof(productids) / sizeof(productids[0]);
int response = linearsearchmyfun(productids, n, x);
(response == -1)? cout<<"Element is not present in array"
: cout<<"Element is present at index " <<response;
return 0;
}

```

### Using C code Example

```#include <stdio.h>

int linearsearchmyfun(int productids[], int n, int x)
{
int i;
for (i = 0; i < n; i++)
if (productids[i] == x)
return i;
return -1;
}

int main(void)
{
int productids[] = { 2, 3, 4, 10, 40 };
int x = 10;
int n = sizeof(productids) / sizeof(productids[0]);
int response = linearsearchmyfun(productids, n, x);
(response == -1) ? printf("Element is not present in array")
: printf("Element is present at index %d",
response);
return 0;
}

```

### Using Java code Example

```class PAKAINFO
{
public static int linearsearchmyfun(int productids[], int x)
{
int n = productids.length;
for(int i = 0; i < n; i++)
{
if(productids[i] == x)
return i;
}
return -1;
}

public static void main(String args[])
{
int productids[] = { 2, 3, 4, 10, 40 };
int x = 10;

int response = linearsearchmyfun(productids, x);
if(response == -1)
System.out.print("Element is not present in array");
else
System.out.print("Element is present at index " + response);
}
}

```

### Using Python3 code Example

```def linearsearchmyfun(productids, n, x):

for i in range (0, n):
if (productids[i] == x):
return i;
return -1;

# Driver Code
productids = [ 2, 3, 4, 10, 40 ];
x = 10;
n = len(productids);
response = linearsearchmyfun(productids, n, x)
if(response == -1):
print("Element is not present in array")
else:
print("Element is present at index", response);

```

### Using C# code Example

```using System;

class PAKAINFO
{
public static int linearsearchmyfun(int[] productids, int x)
{
int n = productids.Length;
for(int i = 0; i < n; i++)
{
if(productids[i] == x)
return i;
}
return -1;
}

public static void Main()
{
int[] productids = { 2, 3, 4, 10, 40 };
int x = 10;

int response = linearsearchmyfun(productids, x);
if(response == -1)
Console.WriteLine("Element is not present in array");
else
Console.WriteLine("Element is present at index "+ response);
}
}
```

### Using PHP code Example

```<?php
function linearsearchmyfun(\$productids, \$x)
{
\$n = sizeof(\$productids);
for(\$i = 0; \$i < \$n; \$i++)
{
if(\$productids[\$i] == \$x)
return \$i;
}
return -1;
}

\$productids = array(2, 3, 4, 10, 40);
\$x = 10;

\$response = linearsearchmyfun(\$productids, \$x);
if(\$response == -1)
echo "Data Element is not present in array";
else
echo "Data Element is present at index " ,
\$response;

?>
