这个怎么编程，我不太懂

1.

#include <stdio.h>
int main()
{
    int n,i,j;
    scanf("%d",&n);
    for (i=1;i<=n;i++)
    {
        for(j=1;j<=i;j++)
        {
            if(j<i)
                printf("%d ",i);
            else
                printf("%d\n",i);
        }
        
    }
    return 0;
}

2.

#include <stdio.h>
int main()
{
    int n,i,j;
    int t = 1;
    scanf("%d",&n);
    for (i=1;i<=n;i++)
    {
        for(j=1;j<=i;j++)
        {
            if(j<i)
                printf("%d ",t);
            else
                printf("%d\n",t);
            t++;
        }
        
    }
    return 0;
}
