Code:
#include stdio.h
#include iostream
#include string.h
void search(char *pat, char *txt)
{
int M = strlen(pat);
int N = strlen(txt);
/* A loop to slide pat[] one by one */
for (int i = 0; i <= N - M; i++)
{
int j;
/* For current index i, check for pattern match */
for (j = 0; j < M; j++)
{
if (txt[i + j] != pat[j])
break;
}
if (j == M) // if pat[0...M-1] = txt[i, i+1, ...i+M-1]
{
printf("Pattern found at index %d \n", i);
}
}
}
/* Driver program to test above function */
int main()
{
char *txt = "AABAACAADAABAAABAA";
char *pat = "AABA";
search(pat, txt);
return 0;
}
Output:
Pattern found at index 0
Pattern found at index 9
Pattern found at index 13
