Two Dimensional Array - Question 5
In this question, we will see how to input numbers in a 3X3 integer matrix (2d array) and find the sum of each row separately in C++ programming. To know more about two dimensional array click on the two dimensional array lesson.
Q5) Write a program in C++ to input numbers in a 3X3 integer matrix (2d array) and find the sum of each row separately.
Program
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int a[3][3], r,c,rs;
cout<<"Enter 9 numbers\n";
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
cin>>a[r][c];
}
}
for(r=0; r<3; r++)
{
rs=0;
for(c=0; c<3; c++)
{
cout<<a[r][c]<<" ";
rs=rs+a[r][c];
}
cout<<" Row Sum = "<<rs<<endl;
}
return 0;
}Output
Enter 9 numbers 5 74 3 2 63 21 7 19 24 5 74 3 Row Sum = 82 2 63 21 Row Sum = 86 7 19 24 Row Sum = 50
