Matrix multiplication in C:
#include<stdio.h>
#include<conio.h>
void main()
{
int a[15][15],b[15][15],c[15][15],row, col, i, j, k;
clrscr();
printf("Enter the number of row of Matrix: ");
scanf("%d", &row);
printf("Enter the number of column of Matrix: ");
scanf("%d", &col);
printf("Enter element of first Matrix: \n");
for(i=0;i<row;i++)
{
for(j=0;j<col;j++)
{
scanf("%d",&a[i][j]);
}
}
printf("Enter elements of Second Matrix: \n");
for (i=0;i<row;i++)
{
for(j=0;j<col;j++)
{
scanf("%d",&b[i][j]);
}
}
printf("multiply of the two matrix: \n");
for(i=0;i<row;i++)
{
for(j=0;j<col;j++)
{
c[i][j]=0;
for(k=0;k<col;k++)
{
c[i][j]= c[i][j]+a[i][k]*b[k][j];
}
}
}
for (i=0;i<row;i++)
{
for(j=0;j<col;j++)
{
printf("%d\t",c[i][j]);
}
printf("\n");
}
getch();
}
Output:
Enter the number of row of Matrix: 2
Enter the number of column of Matrix: 2
Enter element of first matrix:
1 1
2 2
Enter elements of Second Matrix:
1 1
2 2
multiply of the two matrix:
3 3
6 6
