# Input numbers in 2d array and find the sum of each row in C

###### 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 <stdio.h>
#include <conio.h>
int main()
{
int a[3][3], r,c,rs;
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++)
{
rs=0;
for(c=0; c<3; c++)
{
printf("%d ",a[r][c]);
rs=rs+a[r][c];
}
printf(" Row Sum = %d\n",rs);
}
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
