[NetBehaviour] How to display code-based art...

[james morris]

try this just to see what is happening:

--------8<------------

#include<stdio.h>

int main()
{
    int i;
    for(i=0;i <= 999999999;i++){
        printf("i1:%d\n",i);
        for(i=0;i <= 999999999;i++){
            printf("i2:%d\n",i);
            for(i=0;i <= 999999999;i++){
                printf("i3:%d\n",i);
                for(i=0;i <= 999999999;i++){
                    printf("i3:%d\n",i);
                    for(i=0;i <= 999999999;i++){
                        printf("i3:%d\n",i);
                        for(i=0;i <= 999999999;i++){
                        }
                    }
                }
            }
        }
    }
    return 0;
}

--------8<------------

so what you actually wanted was:

--------8<------------

#include<stdio.h>

int main()
{
    int i;
    for(i=0;i <= 999999999;i++){
        int i;
        for(i=0;i <= 999999999;i++){
            int i;
            for(i=0;i <= 999999999;i++){
                int i;
                for(i=0;i <= 999999999;i++){
                    int i;
                    for(i=0;i <= 999999999;i++){
                        int i;
                        for(i=0;i <= 999999999;i++){
                            printf("Hello World");
                        }
                    }
                }
            }
        }
    }
    return 0;
}

--------8<------------

which still does not result in any size difference!
