Q. Write a C program for addition of two 3x3 matrix.
Ans.
/*source code of addition of 3x3 matrix c program*/
#include<stdio.h>
#include<conio.h>
int main()
{
int matA[3][3],matB[3][3],matC[3][3];
int r,c,k;
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
printf("Enter first matrix : ");
scanf("%d", &matA[r][c]);
}
}
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
printf("Enter second matrix : ");
scanf("%d", &matB[r][c]);
}
}
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
matC[r][c]=0;
for(k=0; k<3;k++)
matC[r][c] = matA[r][c] + matB[r][c];
}
}
printf("\n New addition matrix : \n");
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
printf(" %d",matC[r][c]);
printf("\n");
}
getch();
return 0;
}

| Figure: Screen shot for addition of two 3x3 matrix C program |
In simple and easy way output of above program :
Enter first matrix :
1 2 3
1 2 3
4 5 6
7 8 9
Enter second matrix :
2 1 7
2 1 7
4 6 3
8 1 1
New addition matrix :
3 3 10
3 3 10
8 11 9
15 9 10

4. Diagonal sum of two matrix
5. Subtract of two matrix
Try to change the code...there are logical errors
ReplyDeleteThis code is very easy...............
ReplyDeleteThis good but u need to change the background colour
ReplyDelete@Srinidhi
DeleteBackgroud color has been changed.
Can you please explain the need of third for loop in the addition of matrices because it gives the same result without using the third then what is the difference between with and without using third loop.
ReplyDeleteCan you please give me reason to use third for loop in addition of the two matrices because it gives the same result without using third loop.
ReplyDeleteDo any one have a addition of 3*3 matrix using while loop ??
