C language general matrix maximum and minimum number search

#include<stdio.h>
int main()
{
    
    
  int i,j,a[3][4],max,max_row,max_col;
  printf("请输入12个数\n");
  for(i=0;i<3;i++)
	  for(j=0;j<4;j++)
		  scanf("%d",&a[i][j]);
	  max=a[0][0];//核心部分
              for(i=0;i<3;i++)
				  for(j=0;j<4;j++)
				  {
    
    
					 if(max<a[i][j])
					 {
    
    	 max=a[i][j];
					max_row=i;
					max_col=j;
				  }
				  }
	  for(i=0;i<3;i++)
	  {
    
    
		  for(j=0;j<4;j++)
	  printf("%5d",a[i][j]);
	  printf("\n");
      }
printf("最大的数是 %d,它在第 %d 行 第 %d 列\n",max,max_row+1,max_col+1);
}

Comparing the maximum and minimum will generally set the initial number to the maximum or minimum, and compare them one by one. Build a loop and record the subscript of each number.

The function of this code is to search for known matrix input.
