C Program to perform Matrix Addition
You are Here:
Perform Matrix Addition
In the following example, we will add the two given matrices (two-dimensional arrays).
Example
C Compiler
#include <stdio.h>
int main()
{
int i, j;
int arr1[3][3] = {
{1, 1, 1},
{1, 1, 1},
{1, 1, 1}
};
int arr2[3][3] = {
{2, 2, 2},
{2, 2, 2},
{2, 2, 2}
};
int arr3[3][3];
printf("\nMatrix A (3 x 3):\n");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
printf("%d ", arr1[i][j]);
printf("\n");
}
printf("\nMatrix B (3 X 3):\n");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
printf("%d ", arr2[i][j]);
printf("\n");
}
printf("\nMatrix Additon (A + B):\n");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
{
arr3[i][j] = arr1[i][j] + arr2[i][j];
printf("%d ", arr3[i][j]);
}
printf("\n");
}
return 0;
}
Output
Matrix A (3 x 3):
1 1 1
1 1 1
1 1 1
Matrix B (3 X 3):
2 2 2
2 2 2
2 2 2
Matrix Additon (A + B):
3 3 3
3 3 3
3 3 3
In the following example, we will get the values for (3 x 3) Matrices A and B from the user and display the matrix addition.
Example
C Compiler
#include <stdio.h>
int main()
{
int i, j;
int arr1[3][3], arr2[3][3], arr3[3][3];
printf("Enter Matrix A (3 X 3):\n");
for(i=0; i<3; i++)
for(j=0; j<3; j++)
scanf("%d", &arr1[i][j]);
printf("\nEnter Matrix B (3 X 3):\n");
for(i=0; i<3; i++)
for(j=0; j<3; j++)
scanf("%d", &arr2[i][j]);
printf("\nMatrix Additon (A + B):\n");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
{
arr3[i][j] = arr1[i][j] + arr2[i][j];
printf("%d ", arr3[i][j]);
}
printf("\n");
}
return 0;
}
Output
Enter Matrix A (3 X 3):
2 2 2
2 2 2
2 2 2
Enter Matrix B (3 X 3):
3 3 3
3 3 3
3 3 3
Matrix Additon (A + B):
5 5 5
5 5 5
5 5 5
