Find multiplication of two matrix | C-Program

Multiplication of two matrix: 

Tips:

Create neated loop for:

1. 1st matrix.
2.  2nd matix.
3. Mutilpication of matrix.
4. Print matix

Code:

#include<stdio.h>

void main()

{
    int n;

    printf("Enter the size of the matrix:\n");

    scanf("%d",&n);

    int a[n][n],b[n][n],c[n][n],i,j,k,sum;

    printf("Enter elements of 1st matrix:\n");

    for(i=0;i<=n-1;i++)

    {
        for(j=0;j<=n-1;j++)

            scanf("%d",&a[i][j]);
    }

    printf("Enter the elements of 2nd matrix:\n");

    for(i=0;i<=n-1;i++)

    {
        for(j=0;j<=n-1;j++)

            scanf("%d",&b[i][j]);
    }

    printf("The multiplication is:\n");

    for(i=0;i<=n-1;i++)

            for(j=0;j<=n-1;j++)

            {
                sum=0;

                for(k=0;k<=n-1;k++)

                    sum=sum+a[i][k]*b[k][j];

                c[i][j]=sum;
            }

    for(i=0;i<=n-1;i++)

    {
        for(j=0;j<=n-1;j++)

            printf("%d\t",c[i][j]);

        printf("\n");
    }

    getch();
}
