matrix as function argument in cpp code example
Example 1: how to pass an array to a function
#include <stdio.h>
float calculateSum(float age[]);
int main() {
float result, age[] = {23.4, 55, 22.6, 3, 40.5, 18};
result = calculateSum(age);
printf("Result = %.2f", result);
return 0;
}
float calculateSum(float age[]) {
float sum = 0.0;
for (int i = 0; i < 6; ++i) {
sum += age[i];
}
return sum;
}
Example 2: passing a 2d array cpp
#include <iostream>
#include <vector>
using namespace std;
typedef vector< vector<int> > Matrix;
void print(Matrix& m)
{
int M=m.size();
int N=m[0].size();
for(int i=0; i<M; i++) {
for(int j=0; j<N; j++)
cout << m[i][j] << " ";
cout << endl;
}
cout << endl;
}
int main()
{
Matrix m = { {1,2,3,4},
{5,6,7,8},
{9,1,2,3} };
print(m);
Matrix n( 3,vector<int>(4,0));
print(n);
return 0;
}
