Program to find the maximum element in a Matrix in C++
In this problem, we are given a matrix of size nXm. Our task is to create a program to find the maximum element in a Matrix in C++.
Problem Description − Here, we need to simply find the largest element of matrix.
Let’s take an example to understand the problem,
Input
mat[3][3] = {{4, 1, 6},
{5, 2, 9},
{7, 3, 0}}Output
9
Solution Approach
The solution to the problem is by simply traversing the matrix. This is done by using two nested loops, and checking whether each element of the matrix is greater than maxVal. And return the maxVal at the end.
Program to illustrate the working of our solution,
Example
#include <iostream>
using namespace std;
#define n 3
#define m 3
int CalcMaxVal(int mat[n][m]) {
int maxVal = mat[0][0];
for (int i = 0; i < n; i++)
for (int j = 0; j < m; j++)
if (mat[i][j] > maxVal)
maxVal = mat[i][j];
return maxVal;
}
int main(){
int mat[n][m] = {{4, 1, 6},{5, 2, 9},{7, 3, 0}};
cout<<"The maximum element in a Matrix is "<<CalcMaxVal(mat);
return 0;
}Output
The maximum element in a Matrix is 9
