I have the following two-dimensional array of strings.
char matriz[linhas][tamanhoDaString]
Through strcpy I copied a string there.
char *aux = "abc";
strcpy(matriz, aux);
My goal was to set linha 3 to aux .
How can I solve my problem?
Just put the index, so you can specify the position of your 2D array you want to copy the value to:
strcpy(matriz[2], aux);
matriz is not a string: it is an array of strings.
You can not use matriz directly in str* functions; you have to use your elements.
The third element of matriz is matriz[2] , this element is (or rather, can be ) a string.
const char *aux = "abc"; // eu gosto de por o const para o compilador me
// avisar se eu tentar alterar o conteúdo de aux
if (strlen(aux) >= sizeof *matriz) {
// o tamanho de cada elemento de matriz
// nao é suficiente para o comprimento de aux
} else {
strcpy(matriz[2], aux);
}
