I’m solving an exercise where I type values for a matrix 3x3, the print and also display its transpose. The problem is that I am not able to receive fractional values, and comma numbers.
The code I was able to develop is this:
#include <stdio.h>
#include <stdlib.h>
void imprime_matriz(int matriz[3][3])
{
int i,j;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
printf(" %2d ",matriz[i][j]);
}
printf("\n");
}
}
void preenche_matriz(int matriz[3][3])
{
int i,j;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
scanf(" %d ",&matriz[i][j]);
}
}
}
void transposta(int matriz[3][3])
{
int i,j;
int aux[3][3];
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
aux[i][j] = matriz[j][i];
}
}
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
matriz [i][j] = aux[i][j];
}
}
}
int main()
{ int matriz[3][3];
printf("\nDigite os elementos da Matriz:\n\n");
preenche_matriz(matriz);
imprime_matriz(matriz);
transposta(matriz);
printf("\n");
imprime_matriz(matriz);
system("pause");
return 0;
}
Understanding "fractional values" as real numbers then is because you have declared your matrix to be integer numbers. Try declaring your matrix as float or double and not int.

Also note that the transpose of a matrix x[M][N] is a matrix xt[M][N] with any M and N, may or may not be equal, and therefore you can only overwrite the original matrix with the transpose in the particular case of M equal to N.
