    simple stuff

    I'm trying to get this program to multiply two vectors and return the result c[2][2]. I think I have most of this correct, it looks like just my out put that is not making sense. I'm trying to get it to display something like
    2 3
    4 5

    Any help?

    Here's the source
    #include <stdio.h>
    #include <math.h>

    float multi(float a[2][2], float b[2][2], float c[2][2])
    int i,j;
    for (i=0;i<2;i++)
    for (j=0;j<2;j++)
    int i,j;
    float *pc[2][2];
    float a[2][2]={{5,6},{8,2}}, b[2][2]={{5,7},{3,5}};
    float c[2][2];

    for (i=0; i<2; i++)
    for (j=0; j<2; j++)

    printf("%f %f \n", c[2][2]);

    return 0;

    for (i=0; i<2; i++)
        printf("%f  %f \n", c[i][0], c[i][1] );
    > float *pc[2][2];
    This is redundant
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
