Trying to get transpose matrix, not sure what's wrong with my code!

[ECEsasha]

I'm trying to print the transposed matrix of the input matrix, but my output keeps coming out to be:

4 5 6
4 5 6
4 5 6

when I input:

1 2 3
4 5 6
7 8 9

I'm really not sure what it is that's wrong with my code. Any hints would be very helpful!

#include <iostream>
#include <cstdlib>
#include <vector>

using std::vector;


int main(int argc, char** argv){

    vector<vector<int> > v(3, vector<int> (3,0));
   
    int a = atoi(argv[1]);
    int b = atoi(argv[2]);
    int c = atoi(argv[3]);
    int d = atoi(argv[4]);
    int e = atoi(argv[5]);
    int f = atoi(argv[6]);
    int g = atoi(argv[7]);
    int h = atoi(argv[8]);
    int k = atoi(argv[9]);

    v[0][0] = a;
    v[0][1] = b;
    v[0][2] = c;
    v[1][0] = d;
    v[1][1] = e;
    v[1][2] = f;
    v[2][0] = g;
    v[2][1] = h;
    v[2][2] = k;

    std::swap(d,b);
    std::swap(c,g);
    std::swap(f,h);

	for(int i = 0; i< v.size(); i++){
		vector<int> row = v.at(1);
		for(int j = 0; j < row.size(); j++){
			std::cout<<row.at(j)<<'\t';
		}
		std::cout<<'\n';
	}

}

for(int i = 0; i< v.size(); i++){
	vector<int> row = v.at(1);

Are you sure that there should be 1?

Whoops, silly mistake again haha. It should have been an 'i' instead of a 1!

Thanks!

Perhaps a good reason not to use similar looking chars like i and j, or m and n

Make them words, so you can spot these errors straight away, or not make the error at all. Meaningful variable names count a lot towards understanding and self documentation as well.
