Answer:
Here is code in c++.
#include <bits/stdc++.h>
using namespace std;
int main() {
//declare array of size 5x5 
 int arr[5][5];
 // variables to store row sum and column sum
 int row_sum=0,col_sum=0;
 cout<<"please enter the elements of the array: "<<endl;
//reading elements of the array
 for(int i=0;i<5;i++)
 {
 for(int j=0;j<5;j++)
 {
 cin>>arr[i][j];
 }
 cout<<endl;
 }
cout<<"\\sum of each row:"<<endl;
for(int i=0;i<5;i++)
 {
 row_sum=0;
 for(int j=0;j<5;j++)
 {
 //calculating sum of each row
 row_sum=row_sum+arr[i][j];
 }
 //printing the sum of each row
 cout<<"sum of row "<<i+1<<" is :"<<row_sum<<endl;
 }
 cout<<"sum of each column :"<<endl;
 for(int i=0;i<5;i++)
 {
 col_sum=0;
 for(int j=0;j<5;j++)
 {
 //calculating sum of each column
 col_sum=col_sum+arr[j][i];
 }
 //printing the sum of each column
 cout<<"sum of column "<<i+1<<" is :"<<col_sum<<endl;
 }
return 0;
}
Step-by-step explanation:
Declare an array of integer type of size 5x5 to store the element from the user. Read the elements from the user.First travers the array row by row and find the sum of each row and print them.After that travers the array column by column and find the sum of each column and print them.
Output:
please enter the elements of the array: 
23 43 55 23 78 52 64 88 43 56 23 56 343 76 61 59 34 67 90 98 99 12 3 7 123 
 
sum of each row: 
sum of row 1 is :222 
sum of row 2 is :303 
sum of row 3 is :559 
sum of row 4 is :348 
sum of row 5 is :244 
sum of each column : 
sum of column 1 is :256 
sum of column 2 is :209 
sum of column 3 is :556 
sum of column 4 is :239 
sum of column 5 is :416
