I have been away from c++ programming, and decided to start out by making a program that:

a) Accepts input to create a matrix (in form of an array)

b) Puts the matrix in row-echelon form

c) Solves the matrix using backwards substitution

Here is the code with errors when initializing the array:

Code:#include <iostream.h> int main() { int width = 1; int height = 1; cout<<"Enter the number of columns in the augmented matrix: "; cin>>height; width = height + 1; int matrix[width][height]; return 0; }
