Program to print all substrings of a given string in C++
In this tutorial, we will be discussing a program to print all the substring of a given string.
For this we will be given with a string or an array of characters. Our task is to print all the substrings of that particular string.
Example
#include<bits/stdc++.h> using namespace std; //printing all the substrings void print_substr(char str[], int n){ for (int len = 1; len <= n; len++){ for (int i = 0; i <= n - len; i++){ int j = i + len - 1; for (int k = i; k <= j; k++) cout << str[k]; cout << endl; } } } int main(){ char str[] = "abca"; print_substr(str, strlen(str)); return 0; }
Output
a b c a ab bc ca abc bca abca
