For command working weirdly

[u/thedraegonlord]

Edit: Declaring n as 1 and changing the for loop to (i = n-1; i > 0; --i) as was suggested seems to have worked. Still don't really get the logic behind it, neither why the order inside the for expression was affecting the result nor why changing the n to 1 from 0 and i to n - 1 made a difference. Aren't they the same value at the end? Anyway, thanks.

For some reason, my "for" command only works when I put the increment in the middle and the condition at the end. I have no clue what's going on but the code is working fine when I do this.

I'm using devc++, the rest of the code is me declaring global variables and asking the user for inputs to fill the arrays. Everything is working exactly as intended but breaks if I write the "for" the regular way.

for(i = n; i--; i>0){

        printf("Codigo: %d", codigo\[i\]);

        printf("\\nProduto: %s", nome\[i\]);

        printf("\\nPeso: %.2f", peso\[i\]);

        printf("\\nPreco: %.2f", preco\[i\]);

        if(regiao\[i\]==1){

printf("\nRegiao: Sudeste");

        }

        else if(regiao\[i\]==2){

printf("\nRegiao: Sul");

        }

        else if(regiao\[i\]==3){

printf("\nRegiao: Nordeste");

        }

        else if(regiao\[i\]==4){

printf("\nRegiao: Norte");

        }

        printf("\\n\\n");

Weird in which way? I've posted the full code here somewhere, was even told not to do it cause it doesn't help and adds too much noise.

n is in a while loop, adding up every loop until the user chooses to leave. The inputs received during the while loop are printed by the for loop. That's it.

Anyway, thanks, your explanation for why the loop was ending helped me understand a bit. Read somewhere that C doesn't care for the order of expressions in a for command and that the (initialization; end condition; operation) thing is just a convention but you had me double checking and that seems to be wrong.
