Re: [vox] things that really suck about C!



I think you should view C as being nothing more than a platform-independent assembly language.  It astonishes me that it is still used as widely as it is.

I think if anything, C has been a certain detriment to the field of

One calls a function and the arguments are passed by value. Call a
function with an array as an argument, and feel free to modify its
contents!

Certainly, C++ added the idea of reference, but I think Pascal
simplifies these concepts much better. Yet, Pascal seems to be relegated
to the status as a legacy language!

#include <stdio.h>

#define CAP 10

void mod_array(int a[])
{
 a[2] = 5;

void trychange(int a)
{
 a = 2;
}

void reallychange(int *a)
{
 *a = 2;
}

int main() {
 int b[CAP];
 int c;
 int i;

 printf("Load array and change a value\n");
 for (i=0; i < CAP; i++)
   b[i] = i + 20;


 mod_array(b);

 for (i=0; i < CAP; i++)
   printf("b[%d] has value of %d\n",i,b[i]);

 c = 10;

 printf("c has a value of %d\n",c);
 trychange(c);

 printf("c has a value of %d after trychange(c)\n",c);

 reallychange(&c);

 printf("c has a value of %d after reallychange(&c)\n",c);
