###### Two Dimensional Array - Question 9

In this question, we will see how to input numbers in a 3X3 integer matrix (2d array) and print the largest number in each row in C++ programming. To know more about two dimensional array click on the two dimensional array lesson.

Q9) Write a program in C++ to input numbers in a 3X3 integer matrix (2d array) and print the largest number in each row.

#### Program

#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
int a[3][3], r,c,lg,x=0;

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++)
{
x=0;
for(c=0; c<3; c++)
{
cout<<a[r][c]<<" ";
if(x==0)
{
lg=a[r][c];
x=1;
}
else if(a[r][c]>lg)
{
lg=a[r][c];
}
}
cout<<"  Largest Number = "<<lg<<endl;
}
return 0;
}

#### Output

Enter 9 numbers
18
12
5

15
45
38
72

18 12 5   Largest Number = 18
10 15 45   Largest Number = 45
38 72 64   Largest Number = 72
