Flow chart for Program that displays the position or index in the string S where the string T begins , or -1 if S doesn’t contain T

Output:


1.enter the first string: kali
Enter the string to be seareched: li
  second string is found in the first string at 2 position
2.enter the first string:
nagaraju
    Enter the string to be seareched:
    raju
    second string is found in the first string at 4 position 3.enter the first string:
   nagarjuna
   Enter the string to be seareched: ma
-1

Conclusion: The program is error free
