🔺 C Program to Print Right-Aligned Number Triangle Pattern

#include <stdio.h>
int main( )
{
    int num;
    scanf("%d", &num);
    for(int i = 1; i <= num; i++)
    {
        for(int k = num; k >= i; k--)
        {
            printf(" ");
        }
        for(int j = 1; j <= i; j++)
        {
            printf("%d ", j);
        }
        printf("\n");
    }
}
