Answer to Question #47691 in C++ for rishi

Question

write a COLSUM() function in c++ to find sum of each column o a N*M Matrix.

Answer 1

#include <stdlib.h>
#include <iostream>
#include <stdio.h>
#include <cstdlib>
using namespace std;
void ColSum(int **mas, int n, int m);
int main()
{
int n,m;
cout<<"Enter the n: ";
cin>>n;
cout<<"Enter the m: ";
cin>>m;
int **mas = new int* [n];
for (int i = 0; i < n; i++)
mas[i] = new int[m];
cout<<"Enter the array elements: (Array "<<n<<"*"<<m<<"):"<<endl;
for (int i = 0; i < n; i++)
{
for (int j = 0; j < m; j++)
{
cin>>mas[i][j];
}
}
ColSum(mas, n, m);
system("pause");
return 0;
}
void ColSum(int* mas[], int n, int m)
{
int sum = 0;

for (int j = 0; j < m; j++)
{
for (int i = 0; i < n;i++)
{
sum +=mas[i][j];
}
cout<<"Sum of "<<j+1<<" column: "<<sum<<endl;
sum = 0;

}
}
