C++ Program to Count Occurrence of Word in String

Write C++ Program to Count Occurrence of Word in String

// CPP Program to Count Occurrence of Word in String

#include <iostream>
#include <string.h>
#include <stdlib.h>

using namespace std;

int main()
{
	char S1[50], S2[50];
	int index, i, l1, l2, j , Max, Count = 0, flag = 0;

	cout << "Enter String :--> ";
	gets(S1);

	cout << "Enter Word to Search:--> ";
	cin >> S2;

	l1 = strlen(S1);
	l2 = strlen(S2);
	Max = l1 - l2;

	for(i = 0;i <= Max; i++)
	{
		if(strncmp(S1 + i, S2, l2) == 0)
            /* here a and b is considered as array address and a+i means array is
            compared with array b up to the size of substring */
			Count++;
	}

	if(Count != 0)
		cout << "Word Appears " << Count <<" Times";
	else
		cout << "Word Not Found";

	return 0;
}

Output:

Run 1:
Enter String :--> The essens of the programing is the short code
Enter Word to Search:--> the
The Word Appears 2 Times

Run 2:
Enter String :--> The essens of the programing is the short code
Enter Word to Search:--> CODE
Word Not Found
