Idea: Enter a 3*3 two-dimensional array A in the keyboard, then assume that a[0][0] is the maximum value, then compare a[0][0] with a[ 1][ 1] and A [2], and finally output the maximum value and the maximum number of rows.

Reference code:

# include & ltstdio.h & gt

# Definition? n？ three

int？ Master ()

{

int？ a[n][n]，I，j，max，maxi

for(I = 0； I & ltn；; I++)// Keyboard input?

for(j = 0； j & ltn； j++)

scanf("%d "，& ampa[I][j])； ?

max = a[0][0]；

maxi = 0；

for(I = 1； I & ltn；; I++)// ergodic judgment?

if(max & lt； a[i][i])？ {

max = a[I][I]；

maxi = I；

}

Printf ("maximum value is %d, maximum number of rows is %d, \n", max, maxi);

Return? 0;

}

/*

1? 2? three

4? 6? five

7? 9? 2

The maximum value is 6 and the maximum number of rows is 1.
