#include<stdio.h>
int main()
{
    int x,y;
    int sum = 1;
    
    for(x=1;x<=9;x++){
        for(y=1;y<=x;y++){
            sum = x*y;
            printf("%d*%d=%d  ",y,x,sum);
            
        }
        printf("\n");
    
    }    

    return 0;
} 

#include <iostream>
using namespace std;
 
int main()
{
    for(int i=1;i<=9;i++)
    {
        for(int j=1;j<=i;j++)
        {
            cout<<i<<"*"<<j<<"="<<i*j<<" ";
            if(i*j<10)
                cout<<" ";
        }
        cout<<endl;
    }
}
