Matrix Addition C programming using Function

Hello Here i a c Program for matrix multiplication of User defined size. Here we create different function to Read data add the data and display them.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 52

#include<stdio.h> void read(int,int,int [][20]); void add(int,int,int [][20],int [][20],int [][20]); void display(int,int,int [][20]); void main() { int r,c,mat[20][20],sem[20][20],sum[20][20]; printf("Enter the Value of Row and Column:- \n"); scanf("%d %d",&r, &c); printf("Enter the First Matrix:- \n"); read(r,c,mat); printf("Enter the Second Matrix:- \n"); read(r,c,sem); add(r,c,mat,sem,sum); printf("The Sum matrix is:- \n"); display(r,c,sum); } void read(int x,int y,int ma[20][20]) { int i,j; for (i=0;i<x;i++) { for(j=0;j<y;j++) { scanf("%d",&ma[i][j]); } } } void add(int x, int y,int right[20][20],int left[20][20],int ans[20][20]) { int i,j; for (i=0;i<x;i++) { for(j=0;j<y;j++) { ans[i][j]=right[i][j]+left[i][j]; } } } void display(int x,int y, int ma[20][20]) { int i,j; for (i=0;i<x;i++) { for(j=0;j<y;j++) { printf("%d\t",ma[i][j]); } printf("\n"); } }

The Process is Quite simple in add function we pass 3 matrix so that can store the sum in one of the matrix and display it.
