Write a C program that Allow the user to enter the size of t

Write a C++ program that:

Allow the user to enter the size of the matrix such as N.

Call a function to do the following:

Create a vector size n X n

Populate the vector with n²distinct randon integers.

Solution

Solution for problrm (CPP) :-

Program:-

#include<iostream>
#include<vector>
using namespace std;
int main()
{
int n ;
cout<<\"Enter size of the matrix : \";
cin>>n;
vector<vector<int> > vec(n,vector<int>(n));

// looping of the outer vector vec
for (int i = 0; i < n; i++)
{
// loopingof the inner vector vec[i]

for (int j = 0; j < n; j++)
{
vec[i][j] = i*n + j; //Filling the vector which had size n*n
}
}

cout<<\"Matrix values are\"<<endl;
for (int i = 0; i < n; i++)
{
for (int j = 0; j < n; j++)
{
cout<<vec[i][j]<<\"\\t\";
}
cout<<endl;
}
return 0;
}

Output :-

Enter size of the matrix : 4

Matrix values are :-
0 1 2 3
4 5 6 7
8 9 10 11
12 13 14 15

Thank you!
