C ++ program to find indices of all occurrences of one string in other .
#include <iostream> NEW_LINE using namespace std ; void printIndex ( string str , string s ) { bool flag = false ; for ( int i = 0 ; i < str . length ( ) ; i ++ ) { if ( str . substr ( i , s . length ( ) ) == s ) { cout << i << " ▁ " ; flag = true ; } } if ( flag == false ) cout << " NONE " ; }
