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. Thanks in advance.

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

Write your own C program that reads through real matrix, 10x10 dimensioned and finds the smallest element in main diagonal and smallest element in secondary diagonal. Code: #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); }
