How do you Write a C program for matrix?

Answer 1

/* multiplication of a 3*3 matrix*/

#include<stdio.h>

main()

{

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

int i,j,k;

printf("enter the elements in A matrix:\n");

for(i=0;i<=2;i++)

{

for(j=0;j<=2;j++)

{

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

}

}

printf("enter b matrix:\n");

for(i=0;i<=2;i++)

{

for(j=0;j<=2;j++)

{

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

}

}

for(i=0;i<=2;i++)

{

printf("\n");

for(j=0;j<=2;j++)

{

c[i][j]=0;

for(k=0;k<=2;k++)

{

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

}

}

}

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

for(i=0;i<=2;i++)

{

for(j=0;j<=2;j++)

{

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

}

printf("\n");

}

}
