CPP program for if else statement

In this article we will learn to implement a CPP program for if else statement. A C++ program is provided below which accepts a number (integer) from user. If the given number is n and 1 <= n <= 9, then we have to print the word for the given number (for example, if n is 2, we have to print two). If the given number is greater than 9, then print Greater than 9.

Program is as follows:

#include <iostream>
using namespace std;

int main(){
    int n;
    cin >> n;
    if(n>=1 && n<=9){
        if(n==1) cout<<"one";
        if(n==2) cout<<"two";
        if(n==3) cout<<"three";
        if(n==4) cout<<"four";
        if(n==5) cout<<"five";
        if(n==6) cout<<"six";
        if(n==7) cout<<"seven";
        if(n==8) cout<<"eight";
        if(n==9) cout<<"nine";
    }
    else{
        cout<<"Greater than 9";
    }
    return 0;
}

Input and output for the above program are as follows:

Input:
5

Output:
five

------------------
Input:
8

Output:
eight

------------------
Input:
44

Output:
Greater than 9
