Row Sum Of A Matrix

Row sum is a matrix operation in which the elements of each row are added and stored
in a different array.......

Program:


#include<iostream>
#include<iomanip>
#include<windows.h>

using namespace std;

void rowsum(int a[][30],int b[],int m,int n)
{
    int i,j;
    b[m];
    for(i=0;i<m;++i)
    {
        b[i]=0;
        for(j=0;j<n;++j)
        {
            b[i]+=a[i][j];
        }
    }
}

int main()
{
    system("cls");
                                cout<<setw(54)<<"*****-------------------*****\n";
        cout<<setw(54)<<"*****ROW SUM OF A MATRIX*****\n";
                            cout<<setw(54)<<"*****-------------------*****\n";
                            cout<<"\n\n";
                            int a[30][30],b[30],m,n,i,j;
                            cout<<"\tEnter row size: ";
                            cin>>m;
                            cout<<"\tEnter column size: ";
                            cin>>n;
                            cout<<"\n\n\tEnter matrix elements: \n\n";
                            for(i=0;i<m;++i)
                            {
                                 for(j=0;j<n;++j)
                                {
                                    cout<<"\tEnter ["<<i<<"]["<<j<<"] : ";
                                    cin>>a[i][j];
                                }
                            }
                            Sleep(1000);
                            system("cls");
                            cout<<"\n\n\n\t\t\tThe matrix is: \n\n";
                            for(i=0;i<m;++i)
                            {
                                cout<<"\t\t\t";
                                 for(j=0;j<n;++j)
                                 {
                                      cout<<a[i][j]<<" ";
                                 }
                                 cout<<endl;
                            }
                            cout<<"\n\n\t\t\tProcessing.......";
                            Sleep(2200);
                            cout<<"\n\n\n\t\tThe row sum of the matrix is: \n\n";
                            rowsum(a,b,m,n);
                            for(i=0;i<m;++i)
                            cout<<"\t\t\tRow"<<i+1<<" : "<<b[i]<<"\n";
            return 0;
}
