Question

C++ need help with comments and explanation

Ctt co de formasix assay with rowd culuma dize. 6 I mebix should be user input and the other mabix. should randomly escaled. Check if they are equal.

Answer 1

#include<iostream>
#include<cstdlib>
using namespace std;

int main()
{
int r,c;
//reading row and column size
cout<<"Enter row and column size:";
cin>>r>>c;

int u[r][c];//user matrix
int random[r][c];//random matrix

//reading user matrix values from input
cout<<"Enter matrix values:\n";
for(int i=0;i<r;i++)
for(int j=0;j<c;j++)
{
cout<<"Array["<<i<<"]["<<j<<"]:";
cin>>u[i][j];//reading input

}

//now generating random matrix
for(int i=0;i<r;i++)
for(int j=0;j<c;j++)
{
random[i][j] = rand()%100;
}

//displaying both matrices
cout<<"Your matrix:\n";
for(int i=0;i<r;i++){

for(int j=0;j<c;j++)
cout<<u[i][j]<<" ";
cout<<endl;}
cout<<"Random matrix:\n";
for(int i=0;i<r;i++){

for(int j=0;j<c;j++)
cout<<random[i][j]<<" ";
cout<<endl;}

//now checking they are equal are not
bool check=false;
for(int i=0;i<r;i++)
for(int j=0;j<c;j++)
if(u[i][j]!=random[i][j])check=true;

if(check)
cout<<"They are not equal\n";
else
cout<<"They are equal\n";

return 0;
}

output:
Enter row and column size:2 2
Enter matrix values:
Array[0][0]:1
Array[0][1]:2
Array[1][0]:1
Array[1][1]:2
Your matrix:
1 2
1 2
Random matrix:
41 67
34 0
They are not equal
