Program to find the last index of an element of array using recursive function.

 // coded by Vaibhav Yadav

#include <iostream>

#define ll long long

ll index(ll a[],ll size,ll x);

using namespace std;

int main() {

    ll n,i,x;

    cout<<"Enter Your Number of Elements in array: ";

    cin>>n;

    ll a[n];

    for(i=0;i<n;i++){

        cout<<"Enter Your Element no "<<i+1<<": ";

        cin>>a[i];

    }

    cout<<"Enter the element you want to search for: ";

    cin>>x;

    if(index(a,n,x)>=0)

    cout<<"Element Is found at position "<<index(a,n,x)<<endl;

    else

    cout<<"Element is not found"<<endl;

    return 0;

}

ll index(ll a[], ll size, ll x){

    if(a[size-1]==x)

    return size-1;

    else

    index(a,size-1,x);

}

Program to print the smallest word in an sentence (Coding Ninja Solutions)

#include <stdio.h>

#include <string.h> // Here I've to add this header file for strcat() function

int main() {

    char name[]="Vaibhav Yadav is good boy";

    char ccname[]=" "; // This is to add space at the end of sentence so that condition can read it.

    strcat(name,ccname); // this functions append the space to last character

    int i,j,k,min=50,count=0;

    for(i=0;name[i]!='\0';i++){

        if(name[i]!=' '){

        count++;

        }

        else{

            if(count<min)
