## C Program To Add Two Matrices (3 D Array)

Learn How To Add Two Matrices in C Programming. It is important that we should know about the **How A For Loop Works** before getting further with the C Program Code.

Here, you have two 3 – Dimensional Matrices (Integer Arrays) and the Sum of each Element of particular Row and Column must be stored in the Third Array of same Row and Column.

#### C Program To Add Two Matrices

#include<stdio.h> int main() { int arr1[3][3], arr2[3][3], arr3[3][3]; int i, j; printf("Enter First 3*3 Matrix Elements:\n"); for(i = 0; i < 3; i++) { for(j = 0; j < 3; j++) { scanf("%d", &arr1[i][j]); } } printf("\nEnter Second 3*3 Matrix Elements:\n"); for(i = 0; i < 3; i++) { for(j = 0; j < 3; j++) { scanf("%d", &arr2[i][j]); } } printf("\nAddition of Matrices:\n"); for(i = 0; i < 3; i++) { for(j = 0; j < 3; j++) { arr3[i][j] = arr1[i][j] + arr2[i][j]; } } printf("\nThird Matrix Elements:\n"); for(i = 0; i < 3; i++) { for(j = 0; j < 3; j++) { printf("%d\t", arr3[i][j]); } printf("\n"); } printf("\n"); return 0; }
