c - how to print all these blocks? -

i want pyramid image.i can first block. have ideas on how this? in advance.

#include <stdio.h> int main() {     for(int i=0;i<=5;i++)     {        for(int j=0;j<=i;j++)         {         printf("%d",j);         }        printf("\n");          for(int k=5;j<=k;k--)        {         printf("%d",k)         }        for(int z=0;z<=5;z++)         {         printf("%d",z);         }      }    } 

i want this

#include <stdio.h>  int main(void){     int n = 5;      for(int = 1; <= n; ++i){//print n lines         for(int j = 0; j < 2; ++j){//repeated twice             //print sequence of number             for(int k = 1; k <= i; ++k){                 printf("%d", k);             }             //print space             for(int k = 0; k < n - i; ++k){                 printf("  ");//2 times             }             //print reverse sequence of number              for(int k = i; k >= 1; --k){                 printf("%d", k);             }         }         printf("\n");//one line end     }     return 0; }
