Question

Edit : I understand the confusion. But I am not trying to optimize here, as @sergio said, I could not come up with a better word.

—

I have been writing code in JavaScript and PHP for a long time now, that I find it hard sometimes to optimize my code in C.

What I mean by optimizing is writing a program in less code. here is an example:

int i;

srand(time(NULL));

for(i = 0; i < 10; i++){
    printf(" %d ", rand() % 300);
    if(i < 10 - 1){
        printf("|");
    }
}

in Javascript I would have wrote it this way :

var html = ''
for(var i = 0; i < 10; i++){
    html += ' '+Math.floor(Math.random() * 100)+' '+( i == 9 ? '|' : '' )
}

the difference in C is that I had to do the If in an other line, and could not act inline on the string. I hope you get my point.

So how would you write my code?

Thank you.

“Number of lines” is traditionally a poor judge of code, if you cram too much into one line it gets unreadable.

for(i = 0; i < 10; i++)
    printf("%s %d ", i ? "|" : "", rand() % 300);
