How to generate multiplication table in C?

We learn multiplication table from childhood, but to write them in C is a task that everyone can't solve.

This following program generates a multiplication table for user-defined number and range.

#include<iostream>

using namespace std;

int main()

{

    int a=5,b=1,res,limit;

    cout<<"Enter the length of the table\n";

    cin>>limit;

    do

    {

        res=a*b;

        cout<<"\na= "<<a<<" b= "<<b<<" res= "<<res;

        b++;

    }while(b<=limit);

return 0;

}
