#include

#define LEN 50

void inputMatrix (int matrix[LEN][LEN], int row, int col) {
int i,j;
printf ("请输入%d行%d列的矩阵：
", row, col);
for (i=0; i printf ("第%d行：", i+1);
for (j=0; j scanf ("%d", &matrix[i][j]);
}
}
putchar ('
');
return 1;
}

int printMatrix (int matrix[LEN][LEN], int row, int col) {
int i,j;
for (i=0; i for (j=0; j printf ("%d ", matrix[i][j]);
}
putchar ('
');
}
putchar ('
');
return 1;
}

int calcMatrix (int matrix[LEN][LEN], int row, int col) {
int mainDiagonalSum, diagonalSum, max, min;
int i,j;

if (row!=col)
return 0;

mainDiagonalSum = diagonalSum = 0;
max = min = matrix[0][0];

for (i=0; i for (j=0; j if (i==j)
mainDiagonalSum += matrix[i][j];
if (i+j==row-1)
diagonalSum += matrix[i][j];
if (matrix[i][j]>max)
max = matrix[i][j];
if (matrix[i][j] min = matrix[i][j];
}
}

printf ("主对角线之和： %d
", mainDiagonalSum);
printf ("次对角线之和： %d
", diagonalSum);
printf ("最大值： %d
", max);
printf ("最小值： %d
", min);
putchar ('
');

return 1;
}

int main (void) {
int matrix[LEN][LEN], row, col;

row = col = 5;

inputMatrix (matrix, row, col);
printMatrix (matrix, row, col);
calcMatrix (matrix, row, col);

return 0;
}运行结果

为了简便，以下运行示意将矩阵设为3行3列，上方源代码为题主要求的5行5列
