This is the example of c-programming. You can edit and compile code in your own way on clicking button. If you have better solution or you found any error on code, then give us suggestion.

Code Explanation :
This is the example of C program to print the solid rectangular shape using * sign. Before going through the example, You must know about following topics.
Here, we use user defined function to print solid rectangle. We also print hollow rectangle in this example below. In that example also, we use user defined function.
This is basic usage of function and for loop. May viewing this code, you will understand this example.
This same can be done without function.
Program to print solid rectangle without function
/* C program to print solid rectangle star pattern */
#include <stdio.h>
int main()
{
int rows, columns, i, j;
printf("nEnter the number of rows : ");
scanf("%d", &rows);
printf("nEnter the number of columns : ");
scanf("%d", &columns);
printf("n");
for (i = 1; i <= rows; i++)
{
for (j = 1; j <= columns; j++)
{
printf("*");
}
printf("n");
}
return 0;
}
We are representing algorithm and flowchart according to the above code.
Algorithm
SETP 1 : Start
SETP 2 : Declare variable rows,columns i and j
SETP 3 : Read rows and columns
SETP 4 : Initialize i = 1 and j = 1
SETP 5 : Repeat this process until i < rows and
STEP 5.1 : Repeat this process until j <= columns
STEP 5.1.1 : Print "*";
STEP 5.1.2 : j++;
STEP 5.2 : Print "n" to break line
STEP 5.3 : i++;
STEP 6 : end
Flowchart
To print hollow rectangle
/* C program to print hollow rectangle star pattern */
#include <stdio.h>
void hollow_rectangle(int, int);
int main()
{
int rows, columns;
printf("nEnter the number of rows : ");
scanf("%d", &rows);
printf("nEnter the number of columns : ");
scanf("%d", &columns);
printf("n");
hollow_rectangle(rows, columns);
return 0;
}
/* Function to print hollow rectangle*/
void hollow_rectangle(int n, int m)
{
int i, j;
for (i = 1; i <= n; i++)
{
for (j = 1; j <= m; j++)
{
if (i==1 || i==n || j==1 || j==m)
printf("*");
else
printf(" ");
}
printf("n");
}
}
This is same example as above. this program print holow rectangle as given below. you can compile using our IDE.
