Program to find addition or subtraction of matrix using arrays

Program to find addition or subtraction of matrix using arrays 

Program:

#include<stdio.h>

void main()

{

float a[3][3],b[3][3],c[3][3];

int i,j;

printf("Enter numbers for 1st matrix in rowwise manner:\n");

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

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

}

}

printf("Enter numbers for 2nd matrix in rowwise manner:\n");

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

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

c[i][j]=a[i][j]+b[i][j];    // Put  c[i][j]=a[i][j]-b[i][j]; to get subtraction //

}

}

printf("Addition matrix is:\n");

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

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

}

printf("\n");

}

}

Output:

Note:

We know that in an array if we want to add or subtract then we can add or subtract with elements of same row and column number only.
