hi all
can you please write this program ?

1-Declare 8 by 8 integer array.
2-write a function that is named Getmax that will receive the array that was declared in part 1 as a parameter and find the maximum value among array's secondary diagonal elements .The function should return the maximum value.

btw it's not a demand !!
i have no idea about this problem so if you can help to know how to solve it that would be great

```#include <stdio.h> #define NR_ROW      10 #define NR_COL      10 int main(void) { int    i, j; float mat[NR_ROW][NR_COL], min_maindg, min_secdg; printf("Input matrix elements :"); for (i = 0; i < NR_ROW; i++) {   for (j = 0; j < NR_COL; j++) {       printf("\nInput element [%d][%d] : ", i, j);       scanf("%f", &mat[i][j]);   } } min_maindg = mat[0][0]; //min el. is mat(0,0), this is why loop starts from 1     for (i = 1; i < NR_ROW; i++) {           if (mat[i][i] < min_maindg) {                 min_maindg = mat[i][i];         }     } min_secdg = mat[0][NR_COL -1]; for (i = 1; i < NR_ROW; i++) {  if (mat[i][NR_COL-i-1] < min_secdg) {     min_secdg = mat[i][NR_COL-i-1];  } }   printf("\nSmallest el. in main diagonal is: %f",       min_maindg); printf("\nSmallest el. in second diagonal is: %f",       min_secdg); } Shorter version – single run through the matrix: #include <stdio.h> #define NR_ROW    10 #define NR_COL    10 int main(void) {   int    i, j;     float mat[NR_ROW][NR_COL], min_maindg, min_secdg;     printf("\nInput matrix elements :\n");     for (i = 0; i < NR_ROW; i++) {       for (j = 0; j < NR_COL; j++) {         printf("\nInput element [%d][%d] : ", i, j);         scanf("%f", &mat[i][j]);         if (i == 0 && j == 0) {             min_maindg = mat[i][j];         }           if (i == 0 && j == NR_COL - 1) {             min_secdg = mat[i][j];         }           if (i == j) {                 if (mat[i][j] < min_maindg) {                     min_maindg = mat[i][j];                 }           }           if (i == NR_COL - 1 - j) {                 if (mat[i][j] < min_secdg) {                   min_secdg = mat[i][j];                 }           }       }     } printf("\nSmallest element in main diagonal is : %f",       min_maindg); printf("\nSmallest element in second diagonal is : %f",       min_secdg); }```
