CPP program to find transpose of a matrix

Source Code :
#include<iostream>
using namespace std;
int main()
{
int a[2][2],b[2][2],i,j;
cout<<"Enter a matrix: ";
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
cin>>a[i][j];
}
}

for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
b[i][j]=a[j][i];
}
}
cout<<"The transposed matrix is: ";

for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
cout<<b[i][j]<<" ";
}

cout<<" "<<endl<<" ";
}

return 0;

}
