Try with this :

#include <iostream>
#define　 M 　 6

using namespace std;

int main()
{

　 for(int i(1) ; i <= M ; i++)
　 {
　　 for(int j(1) ; j <= M ; j++)
　　 {
　　 　 if (j <= i)
　　 　　 cout << j;
　　 　 else
　　 　　 cout << '*';
　　 }
　　 cout << endl;
　 }
　 return 0;
}
。。。。。。。。。。。。。。。。。。。。。。。

#include <iostream>
#include <string>

void fadeaway(const std::string& a, const std::string& b, std::size_t start_pos=1)
{
    std::size_t size = (a.size() < b.size() ? a.size() : b.size()) + 1;

    for (std::size_t pos = start_pos; pos < size; ++pos)
        std::cout << a.substr(0, pos) << b.substr(pos) << '\n';
}

int main()
{
    fadeaway("123456", "******");
}

Read the documentation for sprintf. Note any requirements for the buffer that is written to.
