Thread: How to code string of same char?

Code:

char line [173];
    int x = -1;
    while(x++ <171)
    {line[x]= '-';}
    puts(line);

Is there a better way to do this?

Probably, look at memset(). But with either method you must also insure that you properly terminate the array to create a string.

Thank you. Zach.

It should work but it looks a bit funny to initialize x with -1 and increase x as long as it is smaller than 171
and indeed don't forget the terminating 0

I think the code looks better if you initialize x with 0 and and increase x as long as it is smaller than 173
For example:

Code:

for(x = 0; x < 173; x++)
    line[x]  = '-';

 line[x] = (char) 0;

oeps, the for statement should count until x < 172 since one byte is needed for the 0 character
