How to address resource (memory) leaks

To address resource leaks in your program, ensure that memory is deallocated on all paths, including error paths.

Example

The following code shows an example of a memory leak:

int main(int argc, char ** argv){
            char * str = malloc(10);
            if (argc>1) {
            str = malloc(20);
            // ...
            }
            printf("Str: %s\n",str);
            free(str);
            return 0;
            }
