###### 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 <stdio.h>
#include <conio.h>

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

printf("Enter 9 numbers\n");
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
scanf("%d",&a[r][c]);
}
}

for(r=0; r<3; r++)
{
x=0;
for(c=0; c<3; c++)
{
printf("%d ",a[r][c]);
if(x==0)
{
lg=a[r][c];
x=1;
}
else if(a[r][c]>lg)
{
lg=a[r][c];
}
}
printf("  Largest Number = %d\n",lg);
}
return 0;
}``````

#### Output

```Enter 9 numbers
18
12
5
10
15
45
38
72
64
18 12 5   Largest Number = 18
10 15 45   Largest Number = 45
38 72 64   Largest Number = 72```
