C language two-dimensional array

C Speech two-dimensional array

The following code is to traverse the values in the two-dimensional array and output

#include <stdio.h>
int main()
{
    
    int array[2][3] = {
    {
    1,2,3},{
    4,5,6}};
    int i,j;
    for(i=0;i<2;i++)// That's ok , Cycle twice 
    {
    
        for(j=0;j<3;j++)// Column , loop 3 Time 
        {
    
           printf("%d %p ",array[i][j],&array[i][j]);// Type the address together 
        }
        putchar('\n');// Line break 
    }
    return 0;
}

Output results

1  0061FF00     2  0061FF04     3  0061FF08
4  0061FF0C     5  0061FF10     6  0061FF14

Example ：

Find the largest number in the following data , And output in the rows and columns

arry[3][4] = {
    134,342,33,43,555,356,27,58,92,36,933,367};

Code up

#include <stdio.h>
int main()
{
    
    int arry[3][4] = {
    134,342,33,43,555,356,27,58,92,36,933,367};
    int i,j;
    int hang,lie;
    int max;
    for(i=0;i<3;i++)// In order to transform more vividly , Output it 
    {
    
        for(j=0;j<4;j++)
        {
    
            printf("%d\t",arry[i][j]);// /t Horizontal tab with table , To look good 
        }
        printf("\n");// Line break 
    }
    max = arry[0][0];// Give the first one to MAX As a reference 
    for(i=0;i<3;i++)// Compare one by one , That's ok 
    {
    
        for(j=0;j<4;j++)// Compare one by one , Column 
        {
    
            if(max < arry[i][j])
            {
    
                max = arry[i][j];
                hang = i;// The line where the record is located 
                lie = j;// The column where the record is located 
            }
        }
    }
    printf(" The maximum number is %d In the %d Walk in %d Column ",max,hang+1,lie+1);// Add 1 In order to , People live from 1 Start , And the computer is from 0 Start 
    return 0;
}

Output result

134     342     33      43
555     356     27      58
92      36      933     367
 The maximum number is 933 In the 3 Walk in 3 Column
