C program to sort a 2D array

Sorting a 2D-array

#include<stdio.h>
#include<string.h>
main()
{
int a[3][3],i,j,k,n,temp;
n=sizeof(a)/sizeof(a[0]);
printf("enter 2D array....\n");
for(i=0;i<n;i++)
for(j=0;j<n;j++)
scanf(" %d",&a[i][j]);
//printf("\n");
printf("array before sorting\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
printf(" %d ",a[i][j]);
printf("\n");
}
for(i=0;i<n;i++)
for(j=0;j<n;j++)
for(k=j+1;k<n;k++)
{
if(a[i][j]>a[i][k])
{
temp=a[i][j];
a[i][j]=a[i][k];
a[i][k]=temp;
}
}
printf("array after sorting\n");
for(i=0;i<n;i++)
{
for(k=0;k<n;k++)
printf("%d ",a[i][k]);
printf("\n");
}
}
