Question:
I am studying C and C++ programming on my own. I have no previous programming experience. I am using Visual C++ 5.0 to run the following example “program 8.12” written in the book Programming in ANSI C, revised edition by S. G. Kochan. But Visual C++ 5.0 would not even compile it. Is this the backward compatibility problem of Visual C++ 5.0? There are 24 errors. The error started from “int i;” in the beginning of main(), it read “C2235 ‘;’ in formal parameter list.
// Program 8.12// Sort an array of intergers into ascending order.#includevoid sort (int a[], int n){ int i, j, temp; for (i = 0; i < n-1; ++i) for (j = i + 1; j < n; ++j) if (a[i] > a[j]) { temp = a[i]; a[i] = a[j]; a[j] = temp; }}void main ()( int i; int array[16] = {34, -5, 6, 0, 12, 100, 56, 22, 44, -3, -9, 12, 17, 22, 6, 11}; void sort (int a[], int n); printf ("The array before the sort: "); for ( i = 0; i < 16; ++i) printf ("%i ", array[i]); sort (array, 16); printf (" The array after the sort: "); for ( i = 0; i < 16; ++i) printf ("%i ", array[i]); printf (" ");}
Answer:
Visual C++ 5.0 is indeed compatible with C and the code you posted looks pretty clean. There was just one problem: the line following void main () has an open parenthasis ("(") instead of an open curly brace ("{"). I changed it to a curly brace and it compiled just fine.
