Question

Write a C++ program to sum of diagonal of square matrix.​

Answer 1

Answer:

#include<iostream>

using namespace std;

int main()

{

int a[5][5],d1sum=0,d2sum=0,m,i,j;

cout<<"Enter size of the square matrix(max 5):";

cin>>m;

cout<<"\nEnter the Matrix row wise:\n";

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

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

cin>>a[i][j];

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

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

{

if(i==j)

d1sum+=a[i][j];

if(i+j==(m-1))

d2sum+=a[i][j];

}

cout<<"\nSum of 1st diagonal is "<<d1sum;

cout<<"\nSum of 2nd diagonal is "<<d2sum;

return 0;

}
