행렬 형식의 선형 방정식을 나타내는 C++ 프로그램

선형방정식을 행렬 형태로 표현하는 C++ 프로그램입니다.

알고리즘

Begin
   1) Take the no of variables n and the coefficients of each variable as input.
   2) Declare a matrix[n][n] and constant[n][1].
   3) Make for loops i = 0 to n-1 and j = 0 to n-1
   to take the coefficients of each variable as the elements of the matrix.
   4) Display the matrix by using nested for loops.
End

   for (int i = 0; i < n; i++) {

출력

Enter the number of variables in the equations: 3
Enter the coefficients of each variable for each equation,
ax + by + cz + ... = d:
1 2 3 4
5 6 7 9
8 5 2 1
Matrix representation is:
1 2 3 x = 4
5 6 7 y = 9
8 5 2 z = 1
