C++ Program to Repeatedly Search the Same Text

This C++ program performs naive string matching without using any specific library functions. A text and a pattern is given as input. The pattern is searched for in the text and all instances of the pattern are given as output.

Here is source code of the C++ Program to Repeatedly Search the Same Text (such as Bible by building a Data Structure). The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

```
//enter string without spaces
```
```
#include<iostream>
```
```
#include<string.h>
```
```
using namespace std;
```
```
 
```
```
int main()
```
```
{
```
```
    char org[100], dup[100];
```
```
    int i, j, k = 0, len_org, len_dup;
```

    cout << "NOTE:Strings are accepted only till blank space.";

```
    cout << "\nEnter Original String:";
```
```
    fflush(stdin);
```
```
    cin >> org;
```
```
    fflush(stdin);
```
```
    cout << "Enter Pattern to Search:";
```
```
    cin >> dup;
```
```
 
```
```
    len_org = strlen(org);
```
```
    len_dup = strlen(dup);
```

    for (i = 0; i <= (len_org - len_dup); i++)

```
    {
```
```
        for (j = 0; j < len_dup; j++)
```
```
        {
```

            //cout<<"comparing '"<<org[i + j]<<"' and '"<<dup[j]<<"'.";

```
            if (org[i + j] != dup[j])
```
```
                break;
```
```
        }
```
```
        if (j == len_dup)
```
```
        {
```
```
            k++;
```

            cout << "\nPattern Found at Position: " << i;

```
        }
```
```
    }
```
```
    if (k == 0)
```

        cout << "\nError:No Match Found!";

```
    else
```

        cout << "\nTotal Instances Found = " << k;

```
    return 0;
```
```
}
```

Output:

$ g++ RepeatedSearch.cpp
$ a.out
