Hello!

I have to make a program that reads two numbers a and b and then displays all the numbers that can be formed by replacing the first and the last digit of b with every single digit of a.

For example,if a is 19 and b = 913 it should display the numbers:

113,911,919,913.

There is my piece of code :

I used 'na' and 'nb' to calculate the number of digits of a and b. Also,I used 2 arrays 'va[12]' and 'vb[12]' to hold the values of every digit in the number.Code:#include<iostream> using namespace std; int main() { int a,b,i = 0,j = 0,na = 0,nb = 0,va[12],vb[12]; cout <<"a = "; cin >> a; cout <<"b = "; cin >> b; while (a) { va[i] = a%10; na++; i++; } while (b) { vb[j] = b%10; nb++; j++; } for (i = na-1;i >= 0;i--) { vb[0] = va[i]; vb[na] = va[i]; for (j = nb - 1; j >= 0;j--){ cout << vb[j] << " " ; } } return 0; }

What's wrong? It doesn't work properly...

Thanks in advance !
