To do: Printing a simple pattern using 2D array row and column of characters

To show: How to nest two for loops constructing the 2D array and then prints the elements

 

 

/* Nesting two for loop */

#include <stdio.h>

 

// function prototype

void DrawBox(int, int);

 

void main(void)

{

// function call, with row = 10, column = 25...

DrawBox(10, 25);

}

 

void DrawBox(int row, int column)

{

int col;

 

// row, execute outer for loop, start with the preset value and decrement until 1

for( ; row > 0; row--)

{

// column, execute inner loop, start with preset col, decrement until 1

for(col = column; col > 0; col--)

// print #....

printf("#");

// decrement by 1 for inner loop, go to new line for new row...

printf("\n");

}

// decrement by 1 for outer loop...then repeat...

}
