C语言如何把rand()产生的随机数存入二维数组

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main(void){
    srand((unsigned)time(NULL));
    int i,j,a[5][5],b;
    
    for(b = 0; b < 25; ++b){
        printf("%d ",10+rand()%91);    
    } 
    a[5][5]=10+rand()%91;

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main(void){
    srand((unsigned)time(NULL));
    int i,j,a[5][5];
    for(i=0;i<5;i++)
    {
       for(j=0;j<5;j++)
        {
          a[i][j] = 10+rand()%91;
          printf("%4d",a[i][j]);
        }
        printf("\n");
    }
}
