Explanation / Answer

#include<stdio.h>
#include<conio.h>
void main()
{
int c[10][10],i,j,a,b;
clrscr();
printf(" Enter Order of Matrix : ");
scanf("%d%d",&a,&b);
printf(" Enter Elements : ");
for(i=0;i<a;i++)
for(j=0;j<b;j++)
scanf("%d",&c[i][j]);
for(i=0;i<a;i++)
{
c[i][b]=0;
for(j=0;j<b;j++)
c[i][b]+=c[i][j];
}
for(j=0;j<b;j++)
{
c[a][j]=0;
for(i=0;i<a;i++)
c[a][j]+=c[i][j];
}
c[a][b]=0;
for(i=0;i<a;i++)
c[a][b]+=c[i][b];
for(i=0;i<a+1;i++)
{
for(j=0;j<b+1;j++)
{
printf("%d",c[i][j]);
printf(" ");
}
printf(" ");
}
getch();
