1. Asks the user to enter an odd positive integer m.
2. Reads m from the user. If the value is not legal, the program repeatedly makes the user type in another value until a legal value of m has been entered.
3. Prints an m x m pattern in the shape of an asterisk. The pattern should appear as a large O printed from copies of the letter O that lies over a large - printed from copies of the character -.
Example:
0 - 0
0 - 0
0 - 0
0 - 0
-----0----
0 - 0
0 - 0
0 - 0
0 - 0
How am i suppose to get the program to do this? I know im supposed to use nested for loops but how am i suppose to get the 0 and - in the lines i need?

#include <iostream> using namespace std;
int main (){ int m; cout<<"Enter m\n"; cin>>m;
int j = 0; for (int i = 0 ; i < 2*m ; i++){ & if (i < m){ & cout.width(i); cout<<"o"; cout.width(m-i+1); cout<<"-"; cout.width(m-i+1); cout<<"o"; cout<<endl; & } else if (i > m) { & cout.width(m*2-i); cout<<"o"; cout.width(i-m+1); cout<<"-"; cout.width(i-m+1); cout<<"o"; cout<<endl; & } else { & for (int i = 0 ; i < m ; i++) cout<<'-'; & cout<<"o"; & for (int i = 0 ; i < m ; i++) cout<<'-'; & cout<<endl; & } }
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
