Answer 1

#include<stdio.h>
void main(){
    int i,j,num=1;
    int a[6][10];
    for (i=1;i<=5;i++){
        for (j=4;j>=i;j--){
            printf("  ");
        }
        for(j=1;j<=2*i-1;j++){
            if(num<10){
                printf("0%d",num);
                a[i][j]=num;
            }else{
                printf("%2d",num);
                a[i][j]=num;
            }
            num+=2;
        }
        printf("\n");
    }
    for (i=4;i>=1;i--){
        for (j=4;j>=i;j--){
            printf("  ");
        }
        for(j=1;j<=2*i-1;j++){
            if(a[i][j]<10){
                printf("0%d",a[i][j]);
            }else{
                printf("%d",a[i][j]);
            }
        }
        printf("\n");
    }
}

纯手打，望采纳！

Answer 2

#include <stdio.h>
int main(void)
{
printf(" 01\n");
printf(" 03 05 07\n");
printf(" 09 11 13 15 17\n");
printf(" 19 21 23 25 27 29 31\n");
printf("33 35 37 39 41 43 45 47 49\n");
printf(" 19 21 23 25 27 29 31\n");
printf(" 09 11 13 15 17\n");
printf(" 07 05 03\n");
printf(" 01\n");

return 0;
}

纯手打，哈哈，娱乐一下，想当年就是这么写的。。。这道题也就用数组还好写一点
