C++ code to find total elements in a matrix
Suppose, we are given a matrix of n rows and m columns. We have to find out the number of elements present in it. We find out the value and display it as output.
So, if the input is like n = 20, m = 15, then the output will be 300.
Steps
To solve this, we will follow these steps −
return n * m
Example
Let us see the following implementation to get better understanding −
#include <bits/stdc++.h>
using namespace std;
#define N 100
int solve(int n, int m) {
return n * m;
}
int main() {
int n = 20, m = 15;
cout<< solve(n, m);
return 0;
}Input
20, 15
Output
300
