Q:

# C program to arrange row elements in ascending order

Given an array, we have to arrange the row elements in ascending order using C program.

Program:

The source code to arrange row elements in ascending order is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully.

``````// C program to arrange row elements in ascending order

#include <stdio.h>
#define ROW 3
#define COL 3

int main()
{
int Matrix[ROW][COL] = {
{ 3, 2, 1 },
{ 5, 4, 6 },
{ 9, 8, 7 }
};

int i, j, k, temp;

printf("Matrix:\n");
for (i = 0; i < ROW; ++i) {
for (j = 0; j < COL; ++j)
printf(" %d", Matrix[i][j]);
printf("\n");
}

// Arrange rows elements in ascending order
for (i = 0; i < ROW; ++i) {
for (j = 0; j < COL; ++j) {
for (k = (j + 1); k < COL; ++k) {
if (Matrix[i][j] > Matrix[i][k]) {
temp = Matrix[i][j];
Matrix[i][j] = Matrix[i][k];
Matrix[i][k] = temp;
}
}
}
}

printf("Matrix after sorting row elements:\n");
for (i = 0; i < ROW; ++i) {
for (j = 0; j < COL; ++j)
printf(" %d", Matrix[i][j]);
printf("\n");
}

return 0;
}``````

Output:

```Matrix:
3 2 1
5 4 6
9 8 7
Matrix after sorting row elements:
1 2 3
4 5 6
7 8 9
```

Explanation:

In the main() function, we created a 3X3 matrix matrix using the 2D array. Then we sorted the elements of the rows and printed the updated matrix on the console screen.
