Matrix addition in C

Matrix addition in C: C program to add two matrices, i.e., compute the sum of two matrices and then print it. Firstly a user will be asked to enter the order of matrix (number of rows and columns) and then two matrices. For example, if a user input order as 2, 2, i.e., two rows and two columns and matrices as
First matrix:
1 2
3 4

Second matrix:

4 5
-1 5
then the output of the program (Summation of the two matrices) is:
5 7
2 9

Matrices are frequently used in programming to represent graph data structure, in solving equations and in many other ways.

C program for matrix addition:

#include<stdio.h>

int main()

{

    int a[3][3],b[3][3],c[3][3],i,j;

    printf("Enter the number of rows and columns of matrix\n");

   scanf("%d%d", &i, &j);

    printf("Enter the value of first matrix;\n");

    for(i=0;i<=2;i++)

    {

        for(j=0;j<=2;j++)

        {

          scanf("%d",&a[i][j]);

        }

    }

     printf("Enter the value of Second matrix;\n");

    for(i=0;i<=2;i++)

    {

        for(j=0;j<=2;j++)

        {

          scanf("%d",&b[i][j]);

        }

    }

     printf("Addition of two matrix \n");

    for(i=0;i<=2;i++)

    {

        for(j=0;j<=2;j++)

        {

          c[i][j]=a[i][j]+b[i][j];

          printf("%d ",c[i][j]);

    }

    printf("\n");}

    return 0;}
