/**
 * C program to print number pattern of 1, 0 at even/odd rows
 */

#include <stdio.h>

int main()
{
    int rows, cols, i, j;

    /* Input rows and columns from user */
    printf("Enter number of rows: ");
    scanf("%d", &rows);
    printf("Enter number of columns: ");
    scanf("%d", &cols);

    for(i=1; i<=rows; i++)
    {
        for(j=1; j<=cols; j++)
        {
            // Print 1 if current row is odd
            if(i%2 == 1)
            {
                printf("1");
            }
            else
            {

Logic to print 1, 0 number pattern at alternate rows

If you look at the pattern carefully you will notice that for all odd rows 1 is printed and for even rows 0 is printed. Hence, before printing numbers inside inner loop, you need to check even odd condition. If the current row is odd then print 1 otherwise 0.
Below is the step by step descriptive logic to print 1, 0 number pattern at alternate rows.

Input number of rows and columns to print from user. Store it in some variable say rows and cols.
To iterate through rows run an outer loop from 1 to rows. The loop structure should look like for(i=1; i<=rows; i++).
Run another inner loop to iterate through columns from 1 to cols. The loop structure should look like for(i=1; i<=cols; i++).
Inside the inner loop before printing any number, we need to check condition. Which is for every odd rows 1 is printed and for every even rows 0 is printed. Hence, check if(i%2 == 1) then print 1 otherwise 0.
Finally, after the inner loop when all columns are printed move to next line. Which is print

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
