Q : Write a function fnmat() which takes matrix, m, n as arguments where matrix is of size mXn with m as rows and n as columns. Function should return the maximum and minimum elements of the matrix. Elements of matrix are of integer type.
Answer :
#include<stdio.h>
#include<conio.h>
#define ROW 5
#define COL 5
