* Matrix Addition:-

#include<stdio.h>
#include<conio.h>
void main()

{

int a[3][3],b[3][3],c[3][3],i,j;
clrscr();

printf("Enter A 3 * 3 matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
scanf("%d",&a[i][j]);
}
}
printf("Enter B 3 * 3 matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
scanf("%d",&b[i][j]);
}
}
for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
c[i][j]=a[i][j]+b[i][j];
}
}
printf("The sum of matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
printf("%d ",c[i][j]);
}
printf("\n");
}
getch();
}

Output:-

* Matrix Multiplication:-

#include<stdio.h>
#include<conio.h>
void main()

{

int a[3][3],b[3][3],c[3][3],i,j,k;
clrscr();

printf("Enter A 3 * 3 matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
scanf("%d",&a[i][j]);
}
}

printf("Enter B 3 * 3 matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
scanf("%d",&b[i][j]);
}
}

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
c[i][j]=0;
for(k=0;k<=2;k++)
c[i][j]=c[i][j]+a[i][k]*b[k][j];
}
}

printf("The multiplication of matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
printf("%d ",c[i][j]);
}
printf("\n");
}
getch();
}

Output:-

* Matrix Swapping:-

#include<stdio.h>
#include<conio.h>
void main()

{

int a[3][3],b[3][3],c,i,j;
clrscr();

printf("Enter A 3 * 3 matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
scanf("%d",&a[i][j]);
}
}

printf("Enter B 3 * 3 matrix:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
scanf("%d",&b[i][j]);
}
}

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
c=a[i][j];
a[i][j]=b[i][j];
b[i][j]=c;
}
}

printf("Values are after swapping:\n");

printf("A matrix values:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
printf("%d ",a[i][j]);
}
printf("\n");
}

printf("B matrix values:\n");

for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)
{
printf("%d ",b[i][j]);
}
printf("\n");
}

getch();

}

Output:-

* Write a Program input 3 * 3 integer array and print upper triangle & lower triangle.

#include<stdio.h>

#include<conio.h>

void main()

{

int a[3][3],i,j;

char ch=' ';

clrscr();

  printf("Enter 3 * 3 matrix:\n");

for(i=0;i<=2;i++)

{

for(j=0;j<=2;j++)

{

scanf("%d",&a[i][j]);

}

}

  printf("Upper traingle:\n");

for(i=0;i<=2;i++)

{

for(j=0;j<=2;j++)

{

   if(i>j)

printf("%c ",ch);

else

printf("%d ",a[i][j]);

}

printf("\n");

}

  printf("lower traingle:\n");

for(i=0;i<=2;i++)

{

for(j=0;j<=2;j++)

{

  if(i<j)

printf("%c ",ch);

else

printf("%d ",a[i][j]);

}

printf("\n");

}

getch();

}
