Question

Write a C++ program to find the sum of all the rows and sum of all the columns in a matrix.

Answer 1

#include<iostream.h>

#include<iomainip.h>

void main()

{

int a[5][5],rsize,csize,i,j,rsum,csum;

cout<<"Enter the order of matrix";

cin>>rsize>>csize;

cout<<"Enter the marix elements"<<endl;

for(i = 0;i<rsize;i++)

for(j = 0;j<csize;j++)

cin>>a[i][j];

for(i = 0;i<rsize;i++)

{

rsum = 0

for(j = 0;j<csize;j++)

rsum = rsum + a[i][j];

cout<<"The sum of "<<i + 1<<"row is"<<rsum<<endl;

}

for(i=0;i<csize;i++)

{

csum =0;

for(j=0;j<rsize;j++)

csum = csum + a[j][i];

cout<<"The sum of"<<i +1<<"column is"<<csum<<endl;

}
