C Language Tasks for Beginners

 

 Code :

#include <stdio.h>
int main()
{
    int i,j;
    for (i = 1; i <= 5; i++)
    {
        for (j = i; j >= 1; j--)
        {
            printf("%d",j);
        }
        printf("\n");
    }
    return 0;
}
  • Header File: #include <stdio.h> is needed to use printf() for printing output.
  • Main Function: The program starts from int main(). It returns 0 to indicate successful completion.
  • Outer Loop (Rows): The outer for loop (i = 1 to 5) controls the number of rows. Each row will print numbers in decreasing order starting from i.
  • Inner Loop (Columns): The inner for loop (j = i to j >= 1) prints numbers in reverse, starting from i and ending at 1.
  • New Line: printf("\n"); moves the output to a new line after printing each row.

Output :

1
21
321
4321
54321
