como apagar uma string?

Recommended Posts


				 scanf(" %[^\n]", &aux);
				 char aux2[101];
									  printf("%d, %s, %d\n", j, aux2,strlen(aux));
									  if(aux[j]=='0'||aux[j]=='1'||aux[j]=='2'||aux[j]=='3'|| aux[j]=='4'||aux[j]=='5'||aux[j]=='6'||aux[j]=='7'||aux[j]=='8'||aux[j]=='9'){

tentei declarar a string no inicio do loop mas nao resultou...alguem me sabe dizer como consigo apagar todos os elementos da string aux2?

Ao definires a variavel, inicializa-a a zeros.

char aux2[101] = ""; // tudo a zero (em C nao ha inicializacao parcial)

What have you tried?
