Do a basic calculation. Because that example, "title" has actually a length of 5, so there should be 15 spaces. Therefore, to center the text, you must insert (15 / 2) = 7 spaces (or 8, if you choose to ring up).
I obtain maybe two dozen request for help with some type of programming or style problem every day. Most have more sense than to send me hundreds of lines that code. If castle do, ns ask lock to uncover the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest regime that demonstrates the error" is a an effective debugging tool.
>> Therefore, to facility the text, you need to insert (15 / 2) = 7 spacesDon"t forget the the field-width needs to incorporate the size of the cable - due to the fact that it"s in the field.
#include #include #include #ifdef _WIN32#include int GetColumnWidth()//GetColumnWidth#elseint GetColumnWidth() return 80;#endifint main() const char *s = "Hey, I"m centered!"; const int total_width = GetColumnWidth(); const int s_width = strlen(s); const int field_width = (total_width - s_width) / 2 + s_width; printf("%*s\n", field_width, s); return 0;//main
