# WAP in C to read two 3*3 matrix and subtract their values and store them into third!

The Program in C to read two 3*3 matrix and subtract their values and store them into third is given below:

``````#include <stdio.h>

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

printf("Enter elements of first 3x3 matrix: \n");
for (i = 0; i < 3; i++) {
for (j = 0; j < 3; j++) {
scanf("%d", &a[i][j]);
}
}

printf("Enter elements of second 3x3 matrix: \n");
for (i = 0; i < 3; i++) {
for (j = 0; j < 3; j++) {
scanf("%d", &b[i][j]);
}
}

for (i = 0; i < 3; i++) {
for (j = 0; j < 3; j++) {
c[i][j] = a[i][j] - b[i][j];
}
}

printf("Subtraction of the matrices: \n");
for (i = 0; i < 3; i++) {
for (j = 0; j < 3; j++) {
printf("%d ", c[i][j]);
}
printf("\n");
}

return 0;
}
``````

## Output:

Enter elements of first 3×3 matrix:
4
5
7
3
8
9
10
3
^[[A 7
Enter elements of second 3×3 matrix:
8
6
54
9
4
6
8
9
2
Subtraction of the matrices:
-4 -1 -47
-6 4 3
2 -6 5

## Pro-Tips💡

This program uses two nested for loops to read the elements of the first 3×3 matrix from the user,

and another two nested loops to read the elements of the second 3×3 matrix.

Then, the program uses two nested for loops again to subtract the corresponding elements of the first and second matrices and store the result in the third matrix.

Finally, the program uses two nested for loops again to print the elements of the third matrix which is the subtraction of the second matrix from the first matrix.
