C++ Basic: Exercise-31 with Solution
Write a C++ program to input a single-digit number and print it in a rectangular form of 4 columns and 6 rows.
Pictorial Presentation:

Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
int main()
{
int x;
cout << "\n\n Make a rectangular shape by a single digit number :\n";
cout << "--------------------------------------------------------\n";
cout<<" Input the number : ";
cin>> x;
cout<<" "<<x<<x<<x<<x<<endl;
cout<<" "<<x<<" "<<" "<<x<<endl;
cout<<" "<<x<<" "<<" "<<x<<endl;
cout<<" "<<x<<" "<<" "<<x<<endl;
cout<<" "<<x<<" "<<" "<<x<<endl;
cout<<" "<<x<<x<<x<<x<<endl;
cout << endl;
return 0;
}
Sample Output:
Make a rectangular shape by a single digit number : -------------------------------------------------------- Input the number : 5 5555 5 5 5 5 5 5 5 5 5555

Why is there no std::stou?
The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
