6.Design numbers rectangle structure

Q. Write a program to generate a following numbers structure:

   (Where user entered number through keyboard, for example if num=5)

                        12345

                        12345

                        12345

                        12345

                        12345

Ans.

/* c program for number rectangle*/

#include<stdio.h>

#include<conio.h>

int main()

{

 int num,r,c;

 printf("Enter loop repeat number(rows): ");

 scanf("%d",&num);
