C: Nested Ifs or Gotos

Question

What is the best way to manage resources for a C program. Should I use a nested if structure or should I use goto statements?

I am aware there is a lot

Answer 1

If by using goto you can avoid writing complex code, then use goto.

Your example could also be written like this (no gotos):

void anotherExample()
{
    char *string1, *string2, *string3, *string4, *string5;
    string1 = string2 = string3 = string4 = string5 = 0;
    if ((string1 = (char*) calloc(STRING_MAX, sizeof(char)))
     && (string2 = (char*) calloc(STRING_MAX, sizeof(char)))
     && (string3 = (char*) calloc(STRING_MAX, sizeof(char)))
     && (string4 = (char*) calloc(STRING_MAX, sizeof(char)))
     && (string5 = (char*) calloc(STRING_MAX, sizeof(char))))
    {
       //important code here
    }

  free(string1);
  free(string2);
  free(string3);
  free(string4);
  free(string5);
}
